r10k checkout from forge fails for 4.1.0 - tag from github v4.1.0 works

[TwizzyDizzy]

Affected Puppet, Ruby, OS and module versions/distributions

• Puppet: n/a
• Ruby: n/a
• Distribution: n/a
• Module version: 4.1.0
• r10k version: 3.5.2

How to reproduce (e.g Puppet code you use)

We're using r10k to fetch modules from the forge. With the current 4.1.0 release our r10k fails to checkout puppetlabs-mongodb when setting the target tag to 4.1.0.

At the same time, when checking out the repository directly from github (see bottom), everything works as expected.

Is it possible, that something went wrong with the publishing in the forge?

Cheers & Thanks in advance

A normal checkout of the corresponding tag.
