IndentationError: unindent does not match any outer indentation level issue python3 script - json output

We have a script in python where use another python tool (open source) to create a .json output , but actually we receive the below issue:
IndentationError: unindent does not match any outer indentation level

So you should have python and json skill to fix this error, so the web app is able to read the json format without issues.
