Can you please check on your environment?
I'm sure all the CI tests passed.

[otiai10]

I just tagged v2.4.1. Please check it out

[gasovn]

Hi!

Same error for me with go1.21.0.

Tag v2.4.1 fixed problem for me, thanks!

[yozachar]

Tag v2.4.1 works, thank you!

[filiprejmus]

How can I install with the 2.4.1 tag? Latest is 2.2.1 I think?
