Azure Update Manager Migration script error: Cannot bind argument to parameter 'ResourceId' because it is an empty string.

Question

Hey guys,

Currently scratching my head as to why I can't proceed here. I'm trying to migrate from Automation Update to Azure Update Manager. So far I've had success with one of the Automation Accounts, but second account fails?

I have made sure I have the correct access for the Automation Account. Any ideas as to why it's complaining? The only difference between the one that worked, and the one that doesn't, is that they're location is different.

I'm currently using the MigrationPrerequisiteScript, but when I enter the ResourceID I grab from properties in the Automation Account. It comes back with this error.

I just copy the script, and then paste into ps. Then enter information that is needed.

I have removed the account and subscription id from the output.
