Value cannot be null

I'm trying to compare two databases and the process fails during "Registering target database" with the following error "Value cannot be null. Parameter name: key". I'm using version "12.2.1.4077 Standard". Help please.

    I just upgraded to 12.2. I had the same outcome under 12.0.33.3389.

    Sorry to hear you're having trouble. There's a couple of things to try here:

    - It's worth upgrading to the latest version - we've fixed a lot of bugs (and added a fair few features) between 12.0.33 and 12.3.1 so there's a decent chance we might have fixed this already
    - If that doesn't work, then clicking on the 'More details' link should give you an option to send in the exception as an error report / alternatively getting in touch with support to figure out the reproduction would be really helpful

    Hi Pradnya,

    Sorry to hear that!

    Can I first double check that you've followed the steps here to ensure your user has the necessary permissions: https://documentation.red-gate.com/display/SC12/Permissions+required+to+use+SQL+Compare

    Should that still not help though, please let us know!

    Hi, 
    I have the same problem when I'm trying to compare two script folders.
    Since I compare folders it can't be authorization issue.
    SQL Compare version is 13.4.5.6953

    Issue solved. One of table's definition had unsupported code.
    Why SQL Compare can't report about problem object? I don't know.
