Power Bi deployment pipeline with Azure Devops and Snowflake

HI gbc40,

According to your description, it seems like you are working with analysis service data source. So I think the data source type part should be 'AnalysisServices'.
For the PowerBIPath, maybe you can try to use ‘relative path’ of the rest API that you used to update the data source:

Full URL: https://api.powerbi.com/v1.0/myorg/datasets/{datasetId}/Default.UpdateDatasources

Relative path: datasets/{datasetId}/Default.UpdateDatasources

BTW, the docuemnt mentions dataset created or modified using the public XMLA endpoint aren't supported. Are you working with XMLA endpoint? If that is the case, you should modify them to use the Azure Analysis Services client library for Tabular Object Model at first.
