Thanks for catching this @s3xysteak
We should not normally be publishing source maps. I believe this slipped in after I ran an extra build command while troubleshooting some issues publishing 1.121. This should be addressed in 1.121.1 which was just published. I'll be opening a separate issue to start taking a look at some better release automation/checks so this sort of thing doesn't happen again shortly.
Please let me know if the new version doesn't fix this

Thank you for such a quick response! In my application, it has been fixed in v1.121.1 so I gonna close the issue.

@jjspace It came back again in v1.122.0 😇

Thanks for bringing it up again @s3xysteak. Not really sure what the cause is, our release guide should be preventing this but maybe something's slipping through. We're not planning to do a minor release this time but this should be resolved on future releases.

@ggetz in addition to potentially reviewing the steps in the release guide I had some other thoughts for more automated prevention

The make-zip build process does not generate the sourcemaps at all but build does.
I see a couple options to fix/prevent this but not sure what's the best process wise?

1. add /Build/**/*.js.map to the .npmignore so it never gets published
   • I think this would work but could also end up being a "band-aid" that bites us later if build and make-zip generate different JS files
2. Update the release guide to say run npm run make-zip again right before the publish steps
3. add a prepublishOnly script to the package.json to run gulp makeZip before every publish to guarantee it's the files we want
   • I think this is the best case? it makes the publish command a bit slower to wait for it to generate the docs and stuff but is probably the safest and most foolproof

Thoughts on some or all of the above changes?

CC @lukemckinstry since you're doing the next release

@jjspace I'm thinking the problem here is that we run some build steps as a part of the test command. Perhaps we should come up with a better strategy for dependent tasks.

In the meantime, I think 1 –

add /Build/**/*.js.map to the .npmignore so it never gets published

– is the most straightforward to prevent this particular issue from showing up. Since it's relatively simple, I don't see why we shouldn't do it.

@jjspace it sounds like you have a solution for this, could you get it in by next Wednesday in advance of the next release?
