NodeBB Startup Error // 502 Bad Gateway

[Sean]

I recently updated a nodebb template file in a theme, and when I restarted NodeBB, it will not start, it keeps crashing.

I am getting 502 Bad Gateway on the website (using nginx proxy)

Here is my log, any ideas?

because your nodebb is shutdown and nobody lissten to 4567 port!

[Sean]

I am trying to start it back up again, and it won't start. It just shuts down when I load the page.

[sanatisharif]

run nodebb with ./nodebb dev and see errors, fix them, then run it with ./nodebb start.

./nodebb dev

Ok, didn't think to use that thanks, this is my error, any idea how to fix it?

[sanatisharif]

ok, run ./nodebb stop and kill any possess that listen to nodebb Port,
you can change nodebb port in config.js file!

[sanatisharif]

after that run ./nodebb dev again

This is usually caused by a syntax error in one of the templates. If templates.js goes into a infinite loop while parsing the templates it prints that not so useful error message. Make sure your template has proper t.js syntax, ie follow the whitespace rules to the letter. Check out one the persona templates for reference.

[Sean]

@baris I figured it was a template error since all these problems happened after editing one of the templates, but I reverted the template back to the working version before my edits, and I just can't seem to get NodeBB to start back up. I'll look into the template again and see if there is any issues I can spot.

[Sean]

Alright, problem fixed, thanks guys.

It was because of the template whitespace/indents messing up since I was copying from a file into the terminal.

Thanks
