Brain-WP/Cortex incompatibility: PHP Fatal error: Uncaught Error: Call to undefined function Brain\did_action()

[wujekbogdan]

After running "vendor/bin/mozart" compose I'm getting the following error:

PHP Fatal error:  Uncaught Error: Call to undefined function Brain\did_action() in /Users/my_user_name/htdocs/wordpress/wp-content/themes/my-tmene-name/vendor/brain/cortex/src/Cortex.php:55

Based on just this error, the error is within the package brain/cortex that you're requiring. It seems that you are trying to call a function within a namespace, while in reality you probably need the global did_action() function. Please share the lines of code that the error is referring to, but I'm afraid that's the case and therefore not a Mozart issue.

@coenjacobs I'm not calling the did_action() function, the library calls this function internally: see Cortex/Cortex.php#L55

Hi,

I'm currently fighting with rubix/ml and Mozart. I think I've run into the same issue, therefore I created a composer project from scratch to demonstrate the issue in isolation.

The function is imported at https://github.com/ChristophWurst/rubix-ml-mozart/blob/1344bfba014c8f2c9b7d4edca5c7cc1fddcf989b/lib/Vendor/Rubix/ML/Datasets/Dataset.php#L17. As you can see here, there the original function got namespaced for the import.

The definition, however, has the original namespace: https://github.com/ChristophWurst/rubix-ml-mozart/blob/1344bfba014c8f2c9b7d4edca5c7cc1fddcf989b/lib/Vendor/Rubix/ML/functions.php#L44.

Hope this makes it easier to debug :v:
