[BUG] AVDAppAttachPublish@1 fails without error message

Describe the bug
I use the task AVDAppAttachPublish@1 in my azure devops pipeline.

With GUI I can setup the task properly, so I understand the chosen "Service connection" has the proper rights.

Unfortunately the step fails and there is no clear error given.

##[debug]Processed: ##vso[telemetry.publish area=MSIX-Packaging;feature=AVDAppAttachPublish]{"SYSTEM_TASKINSTANCEID":"xx","SYSTEM_JOBID":"xx","SYSTEM_PLANID":"xx","SYSTEM_COLLECTIONID":"xxx","AGENT_ID":"8","AGENT_MACHINENAME":"fv-az432-888","AGENT_NAME":"Hosted Agent","AGENT_JOBSTATUS":"Succeeded","AGENT_OS":"Windows_NT","AGENT_VERSION":"4.248.0","BUILD_BUILDID":"1391","BUILD_BUILDNUMBER":"20250108.12","BUILD_BUILDURI":"vstfs:///Build/Build/1391","BUILD_CONTAINERID":"81413060","BUILD_DEFINITIONNAME":"xxx","BUILD_DEFINITIONVERSION":"2","BUILD_REASON":"Manual","BUILD_REPOSITORY_CLEAN":"False","BUILD_REPOSITORY_GIT_SUBMODULECHECKOUT":"False","BUILD_REPOSITORY_NAME":"xxx","BUILD_REPOSITORY_PROVIDER":"TfsGit","BUILD_SOURCEVERSION":"7b3f9e6452468","Version":"2.0.0","AppAttachImagePath":"D:\\a\\1\\a\\AppAttach\\app.vhdx","IsSuccessful":false,"ExceptionMessage":{}}
##[debug]task result: Failed
##[error]TypeError: exceptionMessage.match is not a function
##[debug]Processed: ##vso[task.issue type=error;]TypeError: exceptionMessage.match is not a function
##[debug]Processed: ##vso[task.complete result=Failed;]TypeError: exceptionMessage.match is not a function

So the task fails but the ExceptionMessage property is empty. So the resulted error displays that it is not able to show the exception message from the task itself
