AX 2009 workflow error when editing user permission


I have a problem regarding workflow in AX 2009. We just use the Daily Template in General Ledger workflow configuration. When we are editing the user permission of a specific group, the workflow configuration is throwing the below error.

Infolog for Job Workflow Message processing (5637144829)

Infolog for Task Workflow message processing task (5637171340)



ClrObject static method invocation error.

Exception has been thrown by the target of an invocation.

When we reinstall the workflow, it can create submit, approve or reject. But after a few minutes, the workflow is throwing the error again and what we have configured is not running. Always having a pending status.

Can anyone help me on this? Thanks in advance!
