I've got an app that runs fine locally, but barfs in production. (Classic problem, right?)
In production, the JS isn't firing correctly. When I open up the browser console, I see this error:
net::ERR_CONTENT_LENGTH_MISMATCH
When I look in the network tab of Developer Tools, is shows that it failed on a GET request for text/html.
It's a cryptic error. I've only found two other SO posts that even mention is and they're unsolved. (For the interested: first post and second post)
Any idea (1) what it means or (2) how to resolve it?
I am getting Error: net::ERR_CONTENT_LENGTH_MISMATCH
Have a look at your server logs to determine what the real issue is.
For me the problem lay somewhere between nginx and file permissions:
tail -f /usr/local/var/log/nginx/error.log or run nginx -t to determine your conf location, where you could specify a custom log path.- refresh the asset in your browser, eg
http://localhost:3000/assets/jquery/jquery.js
You may see something like this in the logs:
"/usr/local/var/run/nginx/proxy_temp/9/04/0000000049" failed (13:
Permission denied) while reading upstream for file xyz
Heres how I fixed:
sudo nginx -s stop
sudo rm -rf /usr/local/var/run/nginx/*
sudo nginx
According to this bug report, that error occurs when an external resource length does not match the Content-Length header given in the response.
This might occur because of a misconfigured server, or (as a stretch) maybe some BOM characters got put into the file, or maybe even different lines endings (are you writing on a DOS machine and deploying to a UNIX machine?) may cause issues.
Hope this helps.
I had a similar issue when trying to interpret JSON results. It turned out that somewhere along the line an odd character landed in the database - in this instance the culprit was "â??". It is not clear how this value arrived in the database, but it is likely related to HTML encoding issues - "Â" character showing up instead of " " Either way, after removing the odd characters, the problem was solved.
I had similar issue
[crit] 6889#0: *14817 open() "/var/cache/nginx/proxy_temp/3/02/0000000023" failed (13: Permission denied) while reading upstream
it was because Nginx worker process were not able to access folder /var/cache/nginx/proxy_temp/ - I just changed the folder permissions and everything started working
I had similar issue developing locally on MAMP and using Chrome as browser. Same problematic websites on the live servers had no such issues. First I thought it was MAMP that was playing around and I checked settings like PHP versions mismatch, apache version etc., reinstalled, but the issue remained. At the end I just switched to using Brave browser (was delaying the shift to Brave for a while anyway) and that fixed it for me.
Hope this helps.
