Hi,
We have built an Xtend M3 Transaction to call APIs from M3 and ION API to generate some outbound values. The API seems to be working fine when tested from MITEST:

But when the same API is called from ION API, we are receiving the following error:

Interaction with backend services failed.
Same error from postman as well.
I noticed that when we try to call both M3 API's and ION API's from the same transaction, this issue comes up. I've on ongoing ticket with Infor who working on this issue, but if anyone knows the solution please let me know.
Appreciate any kind of solution/suggestions for the issue.
Thanks,
Suriya
