Buffalo Forums

I am a beginner at using Golang (https://mindmajix.com/go-training) and Buffalo. I am trying to create a password authentication service using the authrecipe from https://github.com/gobuffalo/authrecipe. However, upon trying to run this using buffalo dev, I am receiving the following error from the JSON dump:

ERRO[2018-05-10T14:20:48-04:00] application.html: line 14: _flash.html:

line 3: flash: unknown identifier content_type=text/html db="0s" duration="5.354757ms" human_size="0 B" method=GET params="{}" path=/ render="659.229µs" request_id="fa1ad5b329-b4e23f788b" size="0" status="0"

In line 14 application.html file, there is a reference to the flash folder, and in line 3 of my _flash.html file, there is a variable called flash. Has anyone else received this error? How did you fix it? I have tried to delete the flash command, but that did not resolve the problem and the same error kept appearing.

application.html code:
