Research direction
Locate the file that generates the EXPLAIN command output, likely in the source code for the CLI or REST API. Search for the string 'DESCRIBE [EXTENDED] <SourceId>' and change it to 'DESCRIBE <SourceId> [EXTENDED]'. Also update the similar line for sinks. Verify the fix by running the EXPLAIN command and checking the output.
