After 11/20 our PowerBI started to generate the following error:

Last update failed: {DATE} Unable to connect to the undefined data source.

Underlying error code: -2147467259

Underlying error message: The import List.ConformToPageReader matches no exports. Did you miss a module reference?

Cluster URI: WABI-BRAZIL-SOUTH-redirect.analysis.windows.net

On the local machine all reports work without any problems, when we publish and have the data updated, the error is generated We redid the Gateway configuration and validated the firewall and still have the problem
