Rest API Signal execution with variables

Hello,It looks like there is no analog of RuntimeService.signal(String executionId, Map<String,Object> processVariables)‍ provided by Rest API.I checked the source code and there is next implementation of ExecutionResource.performExecutionAction‍ (line 48) if(ExecutionActionRequest.ACTION_S

One more thing. In the meantime I am trying to use old rest API and to do POST to process-instance/${processInstanceId}/signal with request body like this:
<java>
{
"activityId":"receivetask1",
"variable1":"value",
"variable2":"value"
}
</java>

And the response is <blockcode>{"errorMessage":"Forbidden","statusCode":403}</blockcode>
And even GET to process-instance/${processInstanceId} returns the same. But GET to process-instance/${processInstanceId}/diagram returns expected diagram.

Do you have any idea for this behavior? Do any of old API not available any more?

Any help appreciated,
Yury

Thanks for pointing that out. Indeed, the variables are only used in the signalEventReceived, not the plain old signal. Current workaround is to either use the OLD API or do 2 rest-calls: first set variables and signal in the second call, although this is not an"atomic" operation anymore. I've fixed this on master.

About your second question:


protected Status getAuthenticationFailureStatus() {
    return Status.CLIENT_ERROR_FORBIDDEN;
  }

It seems that you're request does not contain valid login-credentials authenticated… What client are you using? The diagram is returned because this requires NO authentication (to be able to embed in HTML, where an img cannot do BASIC authentication).
