500 Error /api/v2/system/environment

REST API
1

I have a new Bitnami Dreamfactory virtual machine. I’ve recreated the VM a couple of time now and have had the same issue. The VM runs fine for some period of time (hours not days) and then I suddenly start getting a “white” screen. It appears to coincide with a session timeout. I say that only because it happened when I left DreamFactory open without using it and then I’m auto logged out. After digging through the logs, I found that I’m getting a 500 error.

192.168.1.35 - - [11/Oct/2015:15:57:05 +0000] “GET /api/v2/system/environment HTTP/1.1” 500 4519

I saw another post indicating a similar issue. The suggested resolution was to change permissions, but I’m not sure which folder to change.

Thanks,
Craig

Make sure webserver has read/write permissions to storage/ and bootstrap/cache/ directories.

I finally think I tracked this down. When I looked deeper at the error I got from /api/v2/system/environment, I noticed that there was a reference to /opt/bitnami/apps/dreamfactory/htdocs/storage/framework/cache. When I went to that directory, I discovered that some of the subdirectories of that folder had root:root permissions. I ran sudo chown -R daemon:daemon * and lo and behold the site fired back up. I’m not sure what created the root:root permissions.

I’ll continue to monitor as I test and see if it comes back or if it was a problem with the bitnami image to start with.

I’m getting the exact same error, but immediately after installing from github. I cloned the repository, checked out the 2.0.1 version, and followed the instructions in the README.md file. After a variety of issues, I got what appears to be a clean install with postgres as the database, and apache as the web server, remembering to set the permissions and ownership of the recommended directories. In desperation, I even tried setting the entire /opt/dreamfactory directory to the same ownership and permissions, but to no avail.

I get the same 500 server error on the same url. When I run the url via ‘curl’, I get the following:

Since it doesn’t appear to be a permissions issue in my case, I’m stuck as to what to try next.

Any suggestions?

Thanks!

I am having the same issue. Did you find a solution to this? Thanks. Rajiv

chmod -R 2777 storage/ bootstrap/cache/

ok - I changed the permission to the above and it seems to work (for now).

I know this a old but I ran into this error when using Nginx

Make sure you edit your nginx.conf snginx.conf files according to
https://wiki.dreamfactory.com/DreamFactory/Installation/Linux/Apt

server {
    listen 80 default_server;
    listen [::]:80 default_server ipv6only=on;

    root /path/to/dreamfactory/public;
    index index.php index.html index.htm;

For php 7.0
replace with
fastcgi_pass unix:/var/run/php/php7.0-fpm.sock;
