Nx migrate does not work with Angular Material/CDK

Current Behavior

Running nx migrate @angular/material or nx migrate @angular/cdk in the nx workspace fails with Cannot read property 'split' of undefined error.

Expected Behavior

I expect that to work especially if nx at the same time completely blocking my ability to use ng update.

Steps to Reproduce

Run nx migrate @angular/material in the project.

It looks like the fix for this issue fixed it by not trying to execute migrations that would fail in this way.

I’m skeptical whether this really fixes things though; presumably these (in this example) CDK migrations exist for a reason, and should be executed to update application code in their intended way, not skipped?

Just an FYI @FrozenPandaz, for when I run the migration on the latest change I get the following for every single library:

Could not find TypeScript project for project: data-model
......redacted output of 20+ libraries...

      ✓  Updated Angular Material to version 11
    
Successfully finished migration-v11

I don’t know if thats expected?
