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.

To correct this:

- Then navigate back to the SmartObject Tester Tool and refresh the REST Service instance & SmartObjects.

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