Getting databricks-connect com.fasterxml.jackson.databind.exc.MismatchedInputException parse warning

Surajv — Thu, 02 May 2024 06:11:17 GMT

Hi community,

I am getting below warning when I try using pyspark code for some of my use-cases using databricks-connect.

Is this a critical warning, and any idea what does it mean?

Logs:
