Power BI Credential Error

Hi All,

I previously posted about an internal error within power bi service, but now I am experiencing another issue which is :

{"error":{"code":"DM_GWPipeline_Gateway_InvalidConnectionCredentials","pbi.error":{"code":"DM_GWPipeline_Gateway_InvalidConnectionCredentials","parameters":{},"details":[{"code":"DM_ErrorDetailNameCode_UnderlyingErrorCode","detail":{"type":1,"value":"-2147467259"}},{"code":"DM_ErrorDetailNameCode_UnderlyingErrorMessage","detail":{"type":1,"value":"The credentials provided for the Blackbaud source are invalid. (Source at Blackbaud.)"}},{"code":"DM_ErrorDetailNameCode_UnderlyingHResult","detail":{"type":1,"value":"-2147467259"}},{"code":"Microsoft.Data.Mashup.CredentialError.DataSourceKind","detail":{"type":1,"value":"Blackbaud"}},{"code":"Microsoft.Data.Mashup.CredentialError.DataSourceOriginKind","detail":{"type":1,"value":"Blackbaud"}},{"code":"Microsoft.Data.Mashup.CredentialError.DataSourceOriginPath","detail":{"type":1,"value":"Blackbaud"}},{"code":"Microsoft.Data.Mashup.CredentialError.DataSourcePath","detail":{"type":1,"value":"Blackbaud"}},{"code":"Microsoft.Data.Mashup.CredentialError.Reason","detail":{"type":1,"value":"AccessUnauthorized"}},{"code":"Microsoft.Data.Mashup.MashupSecurityException.DataSources","detail":{"type":1,"value":"[{\"kind\":\"Blackbaud\",\"path\":\"Blackbaud\"}]"}},{"code":"Microsoft.Data.Mashup.MashupSecurityException.Reason","detail":{"type":1,"value":"AccessUnauthorized"}}],"exceptionCulprit":1}}} Cluster URI: WABI-UK-SOUTH-redirect.analysis.windows.net Activity ID: 7c76c49b-7bff-44e3-bdd8-ea81a8b14991 Request ID: f5ff67e8-7a29-1789-87e2-0a7dd41707e7 Time: 2026-02-19 09:20:29Z

Looks like another credential error, but I have checked all credentials and its all correct, all my files are on onedrive and its all connected as all my data sources can be seen in PBI desktop. Its only the single report that is having this issue, all my other reports are running and refreshing overnight just fine, so this is a very strange one.

Thanks for any help or guidance on this issue.
