Fabric.Workload.DevGateway Initialization failed

[JosEilersTwyzer]

Hi,

When following the Tutorial 'Back-end implementation guide' I got stuck at step 10, running the DevGateway application. The error I get is as follows:

[2024-07-24 14:10:31.743] [Information] Starting DevGateway...

The error message mentions InvalidParameter and ResourceId, I triplechecked ResourceId in the configuration files but looks like it is correct ( api://localdevinstance/{tenantid}/Fabric.WorkloadSample with {tenantid} replaced ). Any idea in what else could be wrong or is there another problem here?

They made a change so that the original instructions about creating the workload name (eg Fabric.WorkloadSample) are incorrect now - the workload name in the non-prod environments must follow the pattern Org.<your org name> instead of Fabric.<your org name>

@box-turtle: you are correct, it is working now. It seems not all configuration files and the documentation are clear about this naming convention for non-prod environments, hopefully this can be updated.

I double checked my resource URI (not sure why it shows it is not valid for dev mode)

api://localdevinstance//Org.TestWorkload

I'm still seeing this issue. can anyone help??

Hi @vishnu01 in your WorkloadManifest.xml file, property ResourceId and appsettings file, property Audience, you should define it as follows : api://localdevinstance/{tenantid}/Org.TestWorkload with {tenantid} replaced, then you should be good to go.
