Hello,

I'm trying to set up EventNotification on my Fedora 34 server, everything looks fine but for this error on API:

Unrecoverable error:500 Server Error: Internal Server Error for url: https://********/zm/api/host/login.json Traceback:Traceback (most recent call last): File "/var/lib/zmeventnotification/bin/zm_detect.py", line 556, in main_handler() File "/var/lib/zmeventnotification/bin/zm_detect.py", line 335, in main_handler zmapi = zmapi.ZMApi(options=api_options) File "/usr/local/lib/python3.10/site-packages/pyzm/api.py", line 80, in __init__ self._login() File "/usr/local/lib/python3.10/site-packages/pyzm/api.py", line 233, in _login raise err File "/usr/local/lib/python3.10/site-packages/pyzm/api.py", line 203, in _login r.raise_for_status() File "/usr/lib/python3.10/site-packages/requests/models.py", line 960, in raise_for_status raise HTTPError(http_error_msg, response=self)requests.exceptions.HTTPError: 500 Server Error: Internal Server Error for url: https://***********/zm/api/host/login.json

The hooks are working but apparently the API on ZM are not working. I've checked and the checkbox is ticket for API on configuration and the .config files are ok as per the installation guide. I use Apache as webserver. Even if I run Curl I get HTTP500 on get version for API:

I've searched this forum and on Internet but I could not find any clue on recent versions of ZM (I'm using the latest).
Any help is welcome, thanks!

Turn on debug logs for zm. It's a zm problem not zmeventnotification.

Debug logs will help narrow down what the issue could be.

I've turn on debug logs and checked all logs but I cannot see anything more then the error I've already posted. There is no specific log file for the API, maybe I'm wrong but what would be the file to look into the logs for this kind of errors?

/var/log/apache2/error.log, /var/log/zm/cake_error.log /var/log/zm/web_php.log are all possible candidates.

/var/log/apache2/error.log

I don't have "zm" dir, I've only "zoneminder" dir and there is no cake_error.log in there while web_php.log is available but have nothing interesting IMHO, anyway here is the excerpt:

Ok I think I've resolved, the last PHP log made me thinking and I've found the missing package in PHP-APCU which was causing "Call to undefined function apc_fetch()". Installed the package resolved the HTTP500 error.

Thanks to all for your hints

Did you fix this by doing any change configuration file (e.g. config_inc,php)?

Check apache logs and /var/log/zm/cake_error.log
