Troubleshooting Steps

Do a comparison of the working Swagger json file and the non-working Swagger json file and you will notice that there are duplicate or incorrect values specified.

Note this comparison can be done with Win Merge or Beyond Compare to validate if there are any inconsistencies on the json file.
