ConnectionString error for Redshift datasource creation via API

[jiri4282]

Hi all,

I'm encountering an error while trying to create datasource for Amazon Redshift via PowerBI REST API. I have succefully created datasources for SQL Server and the error seems to be in not having connection_details in proper format for Redshift.

dataSourceType = "Extension"

example connectionDetails used tried: 

"{"server":"{not_relevant}.redshift.amazonaws.com:5439", "database":"{somedb}", "kind":"AmazonRedshift"}"

"{"path":"{not_relevant}.redshift.amazonaws.com:5439;{somedb}", "kind":"AmazonRedshift"}"

Error message:

400 Client Error: Bad Request for url: https://api.powerbi.com/v1.0/myorg/gateways/{gatewayId]/datasources. Additional information from API: {'error': {'code': 'DMTS_UnsupportedConnectionStringError', 'pbi.error': {'code': 'DMTS_UnsupportedConnectionStringError', 'parameters': {}, 'details': [], 'exceptionCulprit': 1}}}

Thanks you,

Best Regards,

Jiri

Hi  @jiri4282 ,

In general, the error message 400 code appears to indicate that the content of the request body has a problem, now using the connection string does not match the Power BI design, this can not be used directly with the new one, you must use the matching .

You can try the following rest api link and resend it inside the Report to get a connection string that matches the format as a template to modify, modify the connection string being used.
