Thanks. Are you able to identify the cause of this error? For example, which URL does it occur on? Presumably this is triggered when a PHP error occurs on your site, do you know which error is causing it?
Thanks

My apologies, I was not thinking clearly when I posted and the information was incomplete.
I have a site on a LAMP server where I am testing a plugin (not in the wordpress directory). It works fine except that it throws a fatal error if I open the Customizer. I was able to create the issue again and the details are as below.
The following from wp-debug:
PHP Warning: Undefined array key "line" in /query-monitor/collectors/php_errors.php on line 364
