Could you please provide a reproduction (see Reporting a bug in Meteor)?

[rj-david]

Here is the reproduction: https://github.com/rj-david/meteor-issue-10320

[klaussner]

Thanks, @rj-david. This issue could be related to the changes I made in #10238. However, the login works if I run your reproduction with a devel checkout of Meteor (903bdea). 🤔

[rj-david]

@klaussner, I checked out that commit and got the same error

I also checked out the HEAD of devel and also got the same error

[rj-david]

Ok, I might be running it wrong. I have meteor checked out on the same folder level as my reproduction. Is it right that I executed my reproduction using the following:

../meteor/meteor npm run start

Other things that I need to consider to ensure that I am running from the checked out code instead of the installed meteor?

[Erratum]
The script above still calls the installed meteor

[klaussner]

I think that's right, but I just tried it again and it works with my Meteor checkout: https://streamable.com/6icep.

Thanks, @Antoine-O.

@klaussner, running the npm script called the installed meteor. Sorry, my fault.

I can confirm that the tagged beta.3 is running without problems. There might be a problem when creating the build for download. Any suggestion how can we go on figuring this out?

[Antoine-O]

I have this issue in dev (windows) and production (docker with linux), rollback to beta.2 fixed it. Waiting for beta 4 ;)
