@abhi-shk copy pasting the above data into db.json file and running json-server db.json worked for me.
If you can make a gist of how you are using it with json-server I can help more

Hi @d205 ,
I encountered the same error because i made a silly mistake.

I was using this command
json-server --watch $filename --port $portnumber

It was showing me unsupported source data because my source was incorrect.

The correct command is
json-server --watch $filename.json --port $portnumber

I am sure this will solve your issue.
