Running a bot or scheduler might fail due to an auto-logon error

You might encounter an auto-logon error when you run a bot or scheduler in the IBM RPA client 23.0.19.

Symptoms

After you update the IBM RPA client to 23.0.19, you might encounter the following error when you run a bot or a scheduled run:

Error trying to execute script. Could not execute auto-logon. The data to be decrypted exceeds the maximum for this modulus of 128 bytes.

Causes

IBM RPA version 23.0.19 changes the CredentialProvider DLL. The DLL might not be properly replaced if it's used by a running process, which can cause the auto-logon error.

Resolving the problem

As a workaround, restart the computer. The Agent service replaces the DLL after the restart.
