I got this error message while trying to select the product/API in ION workflow on prem, the used service account has all the security roles. what is the security roles which responsible about this? or how to solve this problem?
There are several different items that could be the issue, these KB's below detail each item. I would start with refresh of the ion metadata. Then the cert and lastly the elastic steps, as that one is a little more difficult. To be able to call an endpoint in ION API, you really only need IONAPI-User. Each app will have its own security. Try the two below and let us know if that fixes it. https://customerportal.infor.com/csmcore?id=kb_article_view&sysparm_article=KB2326478

Also make sure you have the IONAPI-User role yourself. I am not 100% sure but in the UI I think it is using the logged in user rather than the specified Service User.
