The job: "Run_ML_Pipeline" results in an invalid http request:

URL https://[missing region].aether.ms/api/v1.0/subscriptions/xxx/resourceGroups/[missing rg]/providers/Microsoft.MachineLearningServices/workspaces/[missing workspace]/PipelineRuns/PipelineSubmit/xxx for HttpRequest is not correct.

These values are available in a variable group in devops and this group is included in the ci-build-train.yml. Any suggestions on why this is happening and how it should be resolved?
