Any kinda help will Appreciated

Answer 1

So I had the same problem as Mjad, except that I actually configured the contact flow manually, and then exported it and used that JSON object.

The issue was was that in my "Update Contact Attributes" I have a string that I was continually updated every time certain actions were made. So for example, the string was, "Customer_Journey" and then it had a "" for every update within a flow. AWS' system obviously didn't like that character going through whatever system they have.

If you have a slash, change the character. This is the case in spite of the fact that I even tried adding, "\" to fix the issue.

Answer 2

Okay, looks like the Content object is not valid. For starters it ends with a ] character instead of a } But even fixing that it has issues.

I'd suggest creating a flow in the gui and export it, then use the json from that as a template.

Also, check the Flow language documentation to get the syntax and structure correct.
