翻译I think this is some type of generic MuleSoft error message, basically saying that it's either unhappy about the input or output, but I've made the simplest flow that I can, and as far as I know there are no parameters to pass.
The test flow I'm trying to do:
HTTP -> ZenDesk/ListTickets -> Set Payload ("hello world")Things I've looked at:
- I'm using a global config and the connection verifies
- I'm using my password (vs. the security token)
- If I make the password incorrect I get a 401 as expected, same if I use my key instead
- I have admin/API privs in ZenDesk
- I'm able to use the REST API from a browser
- There aren't any input parameters listed for "List Tickets", see doc
- If I do a Set Payload to a simple string afterwards then the return type shouldn't matter
- When doing debugging, with breakpoints on the ZenDesk and SetPayload, it never gets to the Set Payload step
In the browser I get:
null (java.lang.UnsupportedOperationException). Message payload is of type: ZendeskConnector$1In the console I see:
