A JSONArray text must start with '[' at 1 [character 2 line 1]

We are using the client to submit a trigger using the following code:

 
            Payload payload = Payload.Builder.newBuilder()
                    .setSummary(createSummary(operation))
                    .setSource(operation.getAttribute().getId())
                    .setComponent(IdManager.getAncestorId(IdManager.Service.NODE_NODE, operation.getAttribute().getId()))
                    .setGroup(IdManager.getAncestorId(IdManager.Service.NODE_ECU, operation.getAttribute().getId()))
                    .setSeverity(convertHealthToSeverity(operation.getAttribute().getHealth()))
                    .setTimestamp(OffsetDateTime.ofInstant(Instant.ofEpochSecond(operation.getTimestamp()), ZoneOffset.UTC))
                    .setCustomDetails(Json.writeValueToString(operation.getAttribute()))
                    .build();

            TriggerIncident incident = TriggerIncident.TriggerIncidentBuilder
                    .newBuilder(routingKey, payload)
                    .setDedupKey(operation.getAttribute().getId())
                    .setClient(client)
                    .build();
                    
           this.client.trigger(incident);    

The serialized incident as a json looks like this:

{
    "client":"--removed_for_security--",
    "dedup_key":"cu3fbbe4-ne30773e-nnd17182-na11f804",
    "event_action":"trigger",
    "payload":{
       "component":"cu3fbbe4-ne30773e-nnd17182",
       "custom_details":"{\"ecuId\":\"cu3fbbe4-ne30773e\",\"health\":500,\"id\":\"cu3fbbe4-ne30773e-nnd17182-na11f804\",\"nodeId\":\"cu3fbbe4-ne30773e-nnd17182\",\"projectId\":\"cu3fbbe4-np932c1d\",\"read\":{\"type\":\"STRING\"},\"reference\":\"s1_server_disconnected_on_system_initialisation_alarm!\",\"value\":\"Critical\"}",
       "group":"cu3fbbe4-ne30773e",
       "severity":"critical",
       "source":"cu3fbbe4-ne30773e-nnd17182-na11f804",
       "summary":"The value of 's1_server_disconnected_on_system_initialisation_alarm' changed to Critical",
       "timestamp":"2022-07-29T13:45:32Z"
    },
    "routing_key":"--removed_for_security--"
 }

However, we are unexpectedly getting the following error:

com.github.dikhan.pagerduty.client.events.exceptions.NotifyEventException: com.mashape.unirest.http.exceptions.UnirestException: java.lang.RuntimeException: java.lang.RuntimeException: org.json.JSONException: A JSONArray text must start with '[' at 1 [character 2 line 1]

Any ideas?

After digging into the code and following the stack trace I found the error is originating from PagerDutyEventsClient.main(...) on line 80.

This is very random as main seems to be a test class!

public static void main(String[] args) throws NotifyEventException {
        String routingKey = "ROUTING_KEY";
        String dedupKey = "DEDUP_KEY";

        PagerDutyEventsClient pagerDutyEventsClient = create();

        JSONObject customDetails = new JSONObject();
        customDetails.put("field", "value1");
        customDetails.put("field2", "value2");

        Payload payload = Payload.Builder.newBuilder()
                .setSummary("This is an incident test to test PagerDutyEventsClient")
                .setSource("testing host")
                .setSeverity(Severity.INFO)
                .setTimestamp(OffsetDateTime.now())
                .setCustomDetails(customDetails)
                .build();

        List<ImageContext> imageContextList = new ArrayList<>();
        imageContextList.add(new ImageContext("src1"));
        List<LinkContext> linkContextList = new ArrayList<>();
        linkContextList.add(new LinkContext("href", "text"));

        TriggerIncident incident = TriggerIncident.TriggerIncidentBuilder
                .newBuilder(routingKey, payload)
                .setDedupKey(dedupKey)
                .setClient("client")
                .setClientUrl("https://monitoring.example.com")
                .setLinks(linkContextList)
                .setImages(imageContextList)
                .build();

        pagerDutyEventsClient.trigger(incident);

        AcknowledgeIncident ack = AcknowledgeIncident.AcknowledgeIncidentBuilder
                .newBuilder(routingKey, dedupKey)
                .build();
        pagerDutyEventsClient.acknowledge(ack);

        ResolveIncident resolve = ResolveIncident.ResolveIncidentBuilder
                .newBuilder(routingKey, dedupKey)
                .build();
        pagerDutyEventsClient.resolve(resolve);

        ChangeEventPayload changeEventPayload = ChangeEventPayload.Builder.newBuilder()
                .setSummary("This is an change event test to test PagerDutyEventsClient")
                .setSource("testing host")
                .setTimestamp(OffsetDateTime.now())
                .setCustomDetails(customDetails)
                .build();

        ChangeEvent changeEvent = ChangeEvent.ChangeEventBuilder
                .newBuilder(routingKey, changeEventPayload)
                .setLinks(linkContextList)
                .build();

        pagerDutyEventsClient.trackChange(changeEvent);
    }

Line 80 in this is:

ChangeEvent changeEvent = ChangeEvent.ChangeEventBuilder
                .newBuilder(routingKey, changeEventPayload)
                .setLinks(linkContextList)
                .build();

So it appears that the error is caused with this static test class and not even our payload.

So we updated the version to 3.1.2 which seems to be the latest version on maven. The error persists but it now seems to be originating from the response from pager duty:

 private EventResult notifyEvent(PagerDutyEvent event, String api, int retryCount) throws NotifyEventException {
        try {
            HttpRequestWithBody request = Unirest.post(api)
                    .header("Content-Type", "application/json")
                    .header("Accept", "application/json");
            request.body(event);
            HttpResponse<JsonNode> jsonResponse = request.asJson();

            if (log.isDebugEnabled()) {
                log.debug(IOUtils.toString(jsonResponse.getRawBody()));
                // A reset, so we can get the contents from the body that were dumped in the log before
                jsonResponse.getRawBody().reset();
            }

            int responseStatus = jsonResponse.getStatus();
            switch(responseStatus) {
                case HttpStatus.SC_OK:
                case HttpStatus.SC_CREATED:
                case HttpStatus.SC_ACCEPTED:
                    return EventResult.successEvent(JsonUtils.getPropertyValue(jsonResponse, "status"), JsonUtils.getPropertyValue(jsonResponse, "message"), JsonUtils.getPropertyValue(jsonResponse, "dedup_key"));
                case HttpStatus.SC_BAD_REQUEST:
                    return EventResult.errorEvent(JsonUtils.getPropertyValue(jsonResponse, "status"), JsonUtils.getPropertyValue(jsonResponse, "message"), JsonUtils.getArrayValue(jsonResponse, "errors"));
                case RATE_LIMIT_STATUS_CODE:
                case HttpStatus.SC_INTERNAL_SERVER_ERROR:
                    if (doRetries) {
                        return handleRetries(event, api, retryCount, jsonResponse, responseStatus);
                    } else {
                        return EventResult.errorEvent(String.valueOf(responseStatus), "", IOUtils.toString(jsonResponse.getRawBody()));
                    }
                default:
                    return EventResult.errorEvent(String.valueOf(responseStatus), "", IOUtils.toString(jsonResponse.getRawBody()));
            }
        } catch (UnirestException | IOException e) {
            throw new NotifyEventException(e);
        }
    }

The stack does not show which line is causing it but i'm guessing its coming from HttpResponse<JsonNode> jsonResponse = request.asJson();

Any update here?

Any update here?

Version 3.0.8 works for me

3.0.8 not working for me 🙁

[machajdik]

Same here, in 3.1.2.

any idea @dikhan?

[machajdik]

Probably an error in the Unirest HTTP client com.mashape.unirest.unirest-java. Maybe an upgrade to com.konghq.unirest-java is possible @dikhan?

[DodoMorph]

See Pull request #32 issue appears if payload isn't json but an error string

[aravind-farmint]

@machajdik @DodoMorph @salml I am still getting this issue.
Can we please publish a new package ?
