Can you post the error, that is being thrown?

Hi @Nerzal

There is no error on the golang console, however this is what i see in the browsers developer tools

I've found the same error here. I'm not using echo. Instead I was using https://github.com/swaggo/http-swagger. The problem is actually due to https://github.com/swaggo/echo-swagger/blob/master/go.mod and http-swagger depending on swag version 1.8.12. There is a open PR to solve this problem on the http-swagger: https://github.com/swaggo/http-swagger/pull/102 But I actually think they will update these dependencies only after the swag v2 stable release is available. Until then you can build your own html page (like a copy paste with the echo-swagger project, only one file)

SO, just add the following line on the imports section

import (
    _ "<your_mod>/docs" // which is the generated folder after swag init
)
