Hello,

I am getting an error when calling the rest API to post comment. Test below has been done with Postman.

Request:
http://localhost:8080/rest/engine/default/task/a47242e0-0a94-11e9-ad7d-f83441629f6b/comment/create?message=test

Response:
{
“timestamp”: “2018-12-28T11:36:38.305+0000”,
“status”: 500,
“error”: “Internal Server Error”,
“message”: “No message available”,
“path”: “/rest/engine/default/task/a47242e0-0a94-11e9-ad7d-f83441629f6b/comment/create”
}

Why I am getting this error?

Thanks.

I think rest api should be

_http://localhost:8080/**engine-rest**/default/task/a47242e0-0a94-11e9-ad7d-f83441629f6b/comment/create?message=test_

Hi,
I tried it but still not working.

As shown at the documentation you have to provide the content of the comment as a JSON object.
Not as a parameter within the URL.

https://docs.camunda.org/manual/7.9/reference/rest/task/comment/post-task-comment/#request

The engine is embedded in a spring boot Application. Hence the url to access the engine is currently -> rest/engine not engine-rest

I get this error after trying with a Json object

You need to add a header to the call
Content-Type = application/json
