TransferProcessManagerImpl error while running the instance #287

I have set up a basic EDC using the SeedVault and certs.

plugins {
    `java-library`
    id("application")
    alias(libs.plugins.shadow)
}

dependencies {
    implementation(libs.edc.control.api.configuration)
    implementation(libs.edc.control.plane.api.client)
    implementation(libs.edc.control.plane.api)
    implementation(libs.edc.control.plane.core)
    implementation(libs.edc.control.plane.sql)

    implementation(libs.edc.dsp)
    implementation(libs.edc.configuration.filesystem)
    implementation(libs.edc.iam.mock)
	implementation(libs.edc.sql.apache.commons)
	implementation(libs.postgresql)
	implementation(libs.edc.transaction.local)
	implementation(libs.edc.transaction.datasource.spi)

    implementation(libs.edc.management.api)
    implementation(libs.edc.transfer.data.plane.signaling)
    implementation(libs.edc.transfer.pull.http.receiver)
    implementation(libs.edc.validator.data.address.http.data)
    
    implementation(libs.edc.edr.cache.api)
    implementation(libs.edc.edr.store.core)
    implementation(libs.edc.edr.store.receiver)

    implementation(libs.edc.data.plane.selector.api)
    implementation(libs.edc.data.plane.selector.core)
    
    implementation(libs.edc.data.plane.self.registration)
    implementation(libs.edc.data.plane.control.api)
    implementation(libs.edc.data.plane.public.api)
    implementation(libs.edc.data.plane.core)
    implementation(libs.edc.data.plane.http)
}

application {
    mainClass.set("org.eclipse.edc.boot.system.runtime.BaseRuntime")
}

var distTar = tasks.getByName("distTar")
var distZip = tasks.getByName("distZip")

tasks.withType<com.github.jengelman.gradle.plugins.shadow.tasks.ShadowJar> {
    mergeServiceFiles()
    archiveFileName.set("connector.jar")
    dependsOn(distTar, distZip)
}

Using the above config I spin up 2 instance, one provider and consumer with the following configurations:

edc.participant.id=provider
edc.dsp.callback.address=http://localhost:19194/protocol
web.http.port=19191
web.http.path=/api
web.http.management.port=19193
web.http.management.path=/management
web.http.protocol.port=19194
web.http.protocol.path=/protocol
edc.transfer.proxy.token.signer.privatekey.alias=private-key
edc.transfer.proxy.token.verifier.publickey.alias=public-key
web.http.public.port=19291
web.http.public.path=/public
web.http.control.port=19192
web.http.control.path=/control
edc.dataplane.api.public.baseurl=http://localhost:19291/public

edc.datasource.default.user=a
edc.datasource.default.password=
edc.datasource.default.url=jdbc:postgresql://localhost:5433/provider

Similar config for consumer as well with the ports changed.
I'm able to create asset, policy and contract and negotiate it but unable to complete the transfer process.
Looking into the logs, the data plane of the provider shows the following error:

SEVERE 2024-07-10T16:32:13.626474236 StateMachineManager [TransferProcessManagerImpl] error caught
org.eclipse.edc.spi.EdcException: Cannot invoke "Object.hashCode()" because "key" is null
	at org.eclipse.edc.transaction.local.LocalTransactionContext.execute(LocalTransactionContext.java:81)

Meanwhile the consumer service runs fine. Is this because transferprocess is not initiated on consumer that the error is not seen.
Is the cert in the repo still correct ?
This is how I run it.

java -Dedc.keystore=resources/certs/cert.pfx -Dedc.keystore.password=123456 -Dedc.fs.config=resources/config/provider.properties -jar app/build/libs/connector.jar

please attach the transfer request payload and maybe the complete stacktrace. which state reaches the transfer on the consumer side? and on the provider one?

First I complete till contract negotiation to get the contract id, using which I initiate the transfer process request.

curl --location 'http://localhost:29193/management/v3/transferprocesses' \
--header 'Content-Type: application/json' \
--data-raw '{
  "@context": {
    "@vocab": "https://w3id.org/edc/v0.0.1/ns/"
  },
  "@type": "TransferRequestDto",
  "connectorId": "provider",
  "counterPartyAddress": "http://localhost:19194/protocol",
  "contractId": "89298d61-6bb1-46ee-89e3-1124e7873cda",
  "assetId": "assetId",
  "protocol": "dataspace-protocol-http",
  "transferType": "HttpData-PULL"
}'

Output

{
    "@type": "IdResponse",
    "@id": "b5ef5961-eb30-4eb3-bd72-530a1c978ab9",
    "createdAt": 1720699678899,
    "@context": {
        "@vocab": "https://w3id.org/edc/v0.0.1/ns/",
        "edc": "https://w3id.org/edc/v0.0.1/ns/",
        "odrl": "http://www.w3.org/ns/odrl/2/"
    }
}

But the logs show error as follows

the provider data plane is not able to get the private key to sign the EDR token. please ensure that the SeedVaultExtension is loaded correctly at startup

I don't see any other error related to public key except this warning

Do you think this could be an issue ?

if your project is a fork of a sample, I suggest to look at what you changed compared with the working sample

please verify that the seed extension is loaded properly. If not, you could add the private key by yourself into the Vault (or, as a fallback, it could be stored in the config)

It is working when I run it inside the Samples repository, but it doesn't work when I bring the transfer modules outside and run it as separate service. It looks like a configuration issue on my side. Thanks for the support !
