Summer '20 force:source:deploy and force:source:retrieve fail for components that use shared CSS LWC

[lindsayholmes-gears]

Summary

I created a CSS-only LWC to share CSS among multiple LWCs. As soon as other LWCs include the code to import the shared CSS, they can no longer be deployed to or retrieved from the org using the CLI (I've used Workbench as a workaround). The message received reads:

ERROR running force:source:retrieve: Cannot read property 'fileName' of undefined

Steps To Reproduce:

Repository to reproduce: dreamhouse-lwc
Files created in repository sharedCssBug

To reproduce, follow steps in release notes exactly.

Expected result

One should successfully be able to retrieve and deploy myComponent using force:source:deploy and force:source:retrieve.

Actual result

When running force:source:retrieve, the following error message is received:

ERROR running force:source:retrieve: Cannot read property 'fileName' of undefined

Results from --loglevel trace: retrieveTrace.txt
Results from --dev-debug: retrieveDebug.txt

When running force:source:deploy, the following error message is received:

No MODULE named markup://c:cssLibrary found : [markup://c:myComponent]

Results from --loglevel trace: deployTrace.txt
Results from --dev-debug: deployDebug.txt

NOTE: the attached text documents with debug/trace results are from my org where I initially experienced the problem, so the names of components don't match up to the samples. All the trace/debug docs can also be found in the linked repository above.

ERROR running force:source:retrieve: Cannot read property 'fileName' of undefined is definitely a theme with lots of recent issues so we'll get it fixed asap. Thank you!

[saddankiSFDC]

Is there any ETA on this fix?

[jmleep]

Also looking for an ETA on this issue... The only workaround is to deploy the shared CSS component every time you deploy any component that imports it, but you must use the CLI and not the VSCode extensions. It's very frustrating.

[nitinparasa]

+1 on this. A fix will be much appreciated!

[shetzel]

This looks the same as #496 and #400. The fix will be in the next patch release.

[mshanemc]

#496 and #400 are closed now, so I'm closing this one.
