Error with @nrwl/nx/enforce-module-boundaries ESLint rule - Cannot read property 'map' of undefined

[zjkipping]

Current Behavior

run nx lint library-name
Get error logs below:

Cannot read property 'map' of undefined
Occured whille linting C:\....

This occurs while the lib in question has nx module boundaries defined by the nx.json & .eslintrc.json

Expected Behavior

run nx lint library-name
Get actual linting errors/warnings

This can be achieved by setting our lib to a scope that has * for onlyDependOnLibsWithTags. Basically removing the nx module boundaries for the lib and circumnavigating the eslint rule that is breaking.

Steps to Reproduce

Using nx empty workspace with angular added for version 12.7.2 of @nrwl dependencies. Besides this I don't know how to reproduce & cannot share any of the source code of the project. Though I know of other projects that have experienced similar errors in vscode (not the command line like my behavior above).

Failure Logs

Unfortunately the logs in the Current Behavior section is all that is outputted in the console...

Looking into the source code for the rule I realized the depConstraints object we have had no onlyDependOnLibsWithTags property. Adding that property with a value of [] gave us the expected behavior.

Possibly it would be worth having better error handling here in case this bit of the json is missing?

@meeroslav This would be more relevant now that we have banned imports support, as they may not have any tag based constraints. Do you care to take a look?
