How to get error text on ajax request?

Question

JavaScript

Through ajax in jquery I send a post request to the server with yii2 (in the request it is not a small array that is processed on the server) I get an error 500 Internal server error. How can I see the error text? If these are yii logs, then please give an article or explain how to set up so that php errors are visible.
PS: before when this happened, I changed post to get and made a request through the browser and corrected errors, but now when you need to process a large array, this method does not work.
Thank you.

You will not be able to get the text of the php error. It will turn out only to read a log on the server.
