Hello! Thank you all for bringing this to our attention. We'll be taking a look at it! |
|
@samuel-pipelaunch @samwolfe-stripe this looks like a relatively easy fix, apologies for letting this skip through. Do you happen to have a minimal repro that causes this issue? Rather than throwing code over the wall, I'd like to confirm that the fix will address what you're experiencing, if possible. If you don't have a minimal repro, it'd be great if you could manually verify after we push out a fix. |
|
@divmain Thanks for taking a look, I tried to set up a minimal repo but couldn't actually trigger the LWC Language Server to run (not sure what actually causes it to kick off), so unfortunately can only replicate in my local repo. Happy to verify a fix manually |
|
I made a fix within the lightning-language-server repository. To reproduce the problem, just make an LWC, and remove the default export and put something else in. This should cause the server to crash. |
|
I tried the @codythomaszeitler on a sample repository, and I couldn't caused the server to crash |
|
@samuel-pipelaunch Okay, I got the exact error that you mentioned above (minus the version number). I reproduced it in the following manner: Create a brand sfdx project:
You'll have something like this. Replace it with this: You will start to see the exception in your "LWC Language Server" output in vscode: ` TypeError: Cannot read properties of undefined (reading 'location') |
|
@samuel-pipelaunch The reason that it is failing is since the file cannot find a "default export". In this specific scenario, the file also has no classes, which let's it get to the error that you found. The error from what I posted is when there is at least one class in the file. |

I have the same problem, but the stack trace seems to be different. I tried reinstalling the plugin as well. I have downgraded the plugin to V58 and it still crashes.
