Hi Shri Gowtham Tharun Reddy Abbireddy ,

We have determined an old code bug in Selfhosted Integration runtime that results in some configuration files not refreshed in Selfhosted Integration runtime upgrade. This introduces possible incorrect dynamic binding which causes above failure.

The hotfix SHIRs based on 5.25 ~ 5.27 with the fix has been released. You can manually update to these versions (directly update and don't need to uninstall).

Mitigation:

Manually update to below hotfix versions accordingly or wait for auto update:

Hi Shri Gowtham Tharun Reddy Abbireddy ,

Thankyou for using Microsoft Q&A platform and thanks for posting your query here.

As I understand your issue, you are getting a dll related error "Could not load file or assembly" when you are using Self hosted IR and running the ADF pipeline. Please let me know if my understanding is incorrect.

The cause for occurrence of this error is unavailability of Microsoft.IdentityModel.Tokens.dll file in the following folder path of the system in which Selfhosted IR has been installed: *C:\Program Files\Microsoft Integration Runtime\4.0\Gateway\DataScan *

Resolution

• Copy the Microsoft.IdentityModel.Tokens.dll file from *C:\Program Files\Microsoft Integration Runtime\4.0\Gateway\DataScan *subfolder to *C:\Program Files\Microsoft Integration Runtime\4.0\Gateway*folder . If the dll file is not available in DataScan folder then , kindly reinstall the Self hosted IR .
