# TYPO3 Exception 1638264590

## TYPO3 12.4 - 2024-05-09

### Overview

An extension adds to a backend Form own Form Nodes. Form node definition adds the deprecated: RequireJsModules:

Example:

> $resultArray\['requireJsModules'\]\[\] = 'TYPO3/CMS/Extension/JavaScriptFile';

### The Issue

Calling the "Edit" Function in TYPO3 Backend of a record using such own Form Node raises this *LogicException*

### Solution

[see needed migration steps for the Extension maintainer in the TYPO3 Documentation:](https://docs.typo3.org/c/typo3/cms-core/main/en-us/Changelog/12.0/Breaking-96221-DenyInlineJavaScriptInFormEnginesRequireJsModules.html)
