UCCX Rest API - Store Files in Database - Internal Error 500

Hello,

I'm currently trying to upload prompt files to UCCX using the API. The upload to the temporary directory shows successful, but I receive an Internal Error 500 when attempting to Store the File in the Database.

To upload the file, I'm following these steps: https://developer.cisco.com/docs/contact-center-express/#!upload-files-to-a-temporary-folder-for-prompt

Here's the specific error:

I've been doing a lot of searching and I can't seem to find a solution... Any help/direction is appreciated. Thank you in advance.

I just tested your code  with postman and it works. I got the prompt uploaded to temp folder and then moved to UCCX database so I can see it in the appropriate folder in UCCX prompt administration. The only difference in my test that I used the same prompt name. in your example you use test1.wav in step one and temp1.wav in step 2.
