Hi,
We have a Drupal site and for this Drupal site we are showing customized
HTML pages if any 500 errors occurred in the site. This customized 500 html
error page is configured at Nginx server, so that whenever any 500 error
occurs on site, Nginx presents that HTML page.
Now , we don’t want that HTML error page for all the cases even if there
500 errors occurred, instead we need a JSON response. For example
https://mydrupalsite.com/apis and https://mydrupalsite.com/apis/uinque_id
for these two page hits, even if 500 error occurred we don’t want to show
the default HTML 500 error page which is configured at Nginx server level.
But Nginx should present the same HTML 500 error page for all other page
requests if 500 errors occurred while accessing those pages.
Question is can we do any configuration changes at Nginx , so that it will
not do anything even if 500 error occurred for that specific two types of
page request mentioned above while it will still consider other page
requests apart from these two for showing up the HTML error page as per the
configuration if 500 error occurred.
Problem that we are facing - We are handling the 500 error at code level in
Drupal end and we are sending JSON data, but that is not getting displayed
as Nginx taking the control of 500 error and it’s showing up the HTML error
page. We already verified that when we are removing that Nginx 500 error
page configuration, in that case we are getting JSON data that Drupal sent
for 500 errors.
So I think, if somehow we can pass the information to Nginx to not take any
action if 500 error occurred while hitting the
https://mydrupalsite.com/apis or https://mydrupalsite.com/apis/uinque_id
URLs then our job will done, because in that case whatever Drupal is
sending we will be able to see that if 500 error occurred. Please note that
for the URLhttps://mydrupalsite.com/apis/uinque_id , uinque_id is a
parameter and it can be changed.
I have attached the nginx.conf file for your reference.
Please guide me. Thanks in advance. I look forward to hearing from you.
Best Regards,
Kaushal
