The issues seem to stem from the v4.0.0 release of labstack/echo here labstack/echo@6d9e043

I'm thinking this is more an issue with github.com/labstack/echo who seem to have just broken all their existing users 😢 Can you make an issue there?

[michaelperret]

There's a thread on their forum addressing it https://forum.labstack.com/t/problem-with-the-new-update/789/3 and the maintainer seems adamant that this is not an issue with their repository.

It seems like an issue with the dependency management chain somewhere (which I'm confused by as the Gopkg.toml file for this repo specifies v3.3.5)

[erikdubbelboer]

Try using my maintained fork which uses go modules already: https://github.com/erikdubbelboer/realize

👍 I'll take a look, thanks @erikdubbelboer! Speaking of being maintained, any idea what the status of the repo here is? Looks like there hasn't been much activity for a few months now

I'm getting the same issue when trying to go get github.com/oxequa/realize, is there an update for a fix to this?

edit:
It seems to be fixed after tagging golang 1.11 in the Dockerfile:
FROM golang:1.11
