This likely isn't a mockery issue. Please double check your go.mod file features a valid go version.

@LandonTClipp It's issue mockery in docker image. Did you try to reproduce it? go.mod have been generated by command go mod init and it is correct:

module example.com

go 1.21.1

[LandonTClipp]

Apologies, you are right. It seems the Dockerfile is pulling in go 1.20 but your go.mod requires at least 1.21.1. Should be as simple as updating the Dockerfile if you want to send in a PR for that.

@evsamsonov did the new update fix your problem?

[evsamsonov]

Yes, thanks
