Warning: array_key_exists when installing module

[dsdsdsdsdsds]

When installing the module and refreshing the module cache, the following error shows up (2-3 times) at the top of the module page (with debug mode on):
Warning: array_key_exists(): The first argument should be either a string or an integer in /wire/core/WireData.php on line 172

After removing the module, the error is gone again.

Module version 1.1.4
ProcessWire 3.0.210
PHP 7.4

I can't figure it out at the moment, but the error appears when a module that is not installed is listed in required in the module GraphQLFieldtypeOembed.
The workaround is not to list this module (ProcessGraphQL)
