Error on MCSych workflows on marketing instance after a Build Upgrade

[RRafiki]

Hi experts

After upgrading, I'm experiencing an issue. In MOT, the message center workflow - Message Center Execution Instance 2 is errored out. I checked the URL, External Account ID, and the other account information it uses.

All seems to be passed with correct values, but still, the WF is erroring out.

Error Message:

04/19/2023 12:25:42 PM    SCR-160012 Javascript: error while evaluating script 'mcSynch_mcExec2/soapImportBatchEvent'.

04/19/2023 12:25:42 PM    SOP-330011 Error while executing the method 'LogonToRemoteInstance' of service 'nms:extAccount'.

04/19/2023 12:25:42 PM    -55

Appreciate the help or guidance toward remediation.

Thanks

Could be folder permission/access previleges changed after upgrade.

1. Check folder permissions on remote instance for that operator and or previleges
2. Try sending a logontoremoteinstance soap method request through postman or a workflow http request to troubleshoot the error better.

Here is an example of how you can logon to a remote instance https://experienceleague.adobe.com/developer/campaign-api/api/f-decryptPassword.html?hl=logontoremot...
