Thanks Francis for the detailed explanation.
Overriding the nginx 500 error message will not be a solution for us as we
are handling 500 errors in Drupal codebase, and 500 errors can occur in any
file of the codebase, at code level we are handling that and sending the
json response. So incase of, ' /apis ' call or .'apis/unique_id' call if
nginx web server does nothing, then by default the JSON response whatever
Drupal CMS (https://www.drupal.org/) sends will be displayed to the user
and this will solve our problem.
We can not have a dedicated page (either php or html) to display the
response as 500 error messages can occur from any random file of the
codebase. Whenever the 500 error occurs, Drupal CMS (https://www.drupal.org/)
will return a JSON response and that JSON response content can be different
based on the cause of the issue.
For example https://mydrupalsite.com/apis and
https://mydrupalsite.com/apis/uinque_id for these two page hits, even if
500 error occurred we do not want nginx to show the default HTML 500 error
page. In short we want nginx webserver to do nothing and not consider these
two pages while showing 500 errors.
Please let me know if you need any additional information and I look
forward to hearing from you. Thanks in advance.
Best Regards,
Kaushal
