Callback pathItems are missing in OpenAPI Instance due to decoding issue

[abdelfetah18]

I’ve declared some callbacks in the OpenAPI definition, but when I try to print them, the callback path items are missing. It seems like this might be an encoding issue, causing the paths not to be properly parsed or included when the file is read.

Here’s my test file for reference:
