Serialization of 'WeakMap' is not allowed

[Eduardo-Morales-Alberti]

Error on git hook using grumphp after update to 2.9.0.
Error message:

Serialization of 'WeakMap' is not allowed

PHP version: 8.1.9
Grumphp version: v1.5.1

I know that the information is not enough. Could you give me an explanation of what information should I post here?

I also created an issue on monolog, because I am not sure if it is an issue of monolog or grumphp.

Seems like related to the serialization of the log by the module grumphp phpro/grumphp#1065

[Eduardo-Morales-Alberti]

To run processes in parallel, we use amphp/parallel in combination with serializable-closure.
This serializable-closure is serializing the context of the closure, which might include the logger.

For example, the git_commit_message here will have a dependency to gitonomy, which is configured with a logger (monolog).
Therefore, the serializable-closure will try to serialize both gitonomy and monolog into it's context.
It's not like we are actively willing to serialize the logger in there, but it's part of the dependency tree.
