Nginx return an empty json object with fake 200 status code
error_page 404 =200 @empty_json;location @empty_json { return 200 "{}";}Reference:
You can always create a file in your document root called e.g. empty.json which only contains an empty object {}
Then in your nginx configuration add this line in your location block
try_files $uri /empty.json;( read more about try_files )
This will check if the file requested by the client exists and if it does not exist it just shows empty.json instead. This produces a 200 HTTP OK and shows a {} to the requesting client.
