Error when trying expand

[pommelinho]

Hey!

I created some relation tuples by using the REST API.
I also checked a relation via https://www.ory.sh/keto/docs/reference/api#check-a-relation-tuple. However the expand query is not working for me.

When doing
curl -H "Content-Type: application/GET http://127.0.0.1:4466/expand?namespace=team&object=productowner&relation=member

i get
{"error":{"code":400,"status":"Bad Request","message":"strconv.ParseInt: parsing \"\": invalid syntax"}}

Any ideas what i am doing wrong?

I am pretty sure that expand requires the max-depth parameter, which is wrongly not marked as required in the API documentation: https://www.ory.sh/keto/docs/reference/api/#parameters-1

[zepatrik]

Also that message should include the parameter name to make debugging easier. Would you be up for the challenge? The changes would be required here:

keto/internal/expand/handler.go

Line 78 in 1e04746

depth, err := strconv.ParseInt(r.URL.Query().Get("max-depth"), 0, 0)

hey thanks for your reply.

but also when i do

curl -H "Content-Type: application/GET" http://127.0.0.1:4466/expand?namespace=team&object=productowner&relation=member&max-depth=1
the same error is thrown

It might be related to some bash escape problems then maybe? & means that the command should run in the background. Either try to escape/quote or just use

curl -G --silent \
     --data-urlencode "namespace=files" \
     --data-urlencode "relation=access" \
     --data-urlencode "object=/photos/beach.jpg" \
     --data-urlencode "max-depth=3" \
     http://127.0.0.1:4466/expand

as in https://www.ory.sh/keto/docs/guides/expand-api-display-who-has-access

The docs code samples are tested in the CI so I am pretty sure it works 😉

Thanks worked! ;-)

curl -H "Content-Type: application/GET" 'http://127.0.0.1:4466/expand?namespace=team&object=productowner&relation=member&max-depth=3'
