Logic comes a long way for most of the integration thing in Dynamics 365 FO. Its provides a good set of connectors to develop inbound/outbound integration process. While troubleshooting any error is not so easy while it comes to the logic app for new people. I will be sharing some the common error which I faced during development and hopefully, that will helpful for you guys too.
You have used certain users in Logic apps while creating API connections. while that users don't have access to target AX system.
Check the used in target/Source AX system if the user doesn't exist import the same with admin or proper access. If the user exists then check its access.
I will keep posting any error which I faced with a solution that works for me and I hope that may work for you as well. If you are getting other error, put that in the comment section and I will try to find a solution for you.
