display_errors setting being set to 1 does not show errors in browser.

[dennis-fedco]

What ZF application I'm using when issue happen ?

• Mezzio 3

What PHP version you're using?

• PHP 7.4

What ErrorHeroModule version you're using?

• ^2.0

What Database you're using?

• MySQL version 8.0

Expected behavior

Show exact error message in the browser, and log the error message in the error log.

Actual behavior

No error is shown, but my application has null values when I expect values. The exact error message is not shown explicitly even though effects of the error are evident by observing that my application is not working as expected.

Steps/Codes to reproduce the behavior

When in the hero config file I set ['display-settings']['display_errors'] to 0, the exact error of the application is written into the log, which is helpful in debugging the error. But when I set ['display-settings']['display_errors'] to 1, my application does not show explicit error in the browser, and no error message is written into the log, even though it is evident that my application is affected by the (unknown/unlogged) error.

Thus I feel like there is more to ['display-settings']['display_errors'] setting than I am aware of. What happens when ['display-settings']['display_errors'] is set to 1, because I do not see the error in the browser, or any of the logs.

Looking in the ErrorHeroModule code briefly it looks like the setting being 0 turns off ErrorHeroModule handling of the error and pushes it back to MVC module. I am not sure what it means, but it may explain why error is not logged, and why I may not be getting an error message displayed in my browser.

I can't reproduce, when I set display_errors to 1, it display the error:

and save the log to db:

For saving same error to db, it uses interval for new record:

// config/autoload/mezzio-error-hero-module.local.php
<?php 

return [
    // ...
   'logging-settings' => [
        'same-error-log-time-range' => 86400,
    ],
    // ...
];

Please also check if cache is enabled.
