Describe the Bug

I am encountering an issue with Payload CMS where documents containing large text fields are not saving properly. When attempting to save such documents, the request remains pending indefinitely and the document is not saved. This issue persists despite several attempts to resolve it through various configuration changes. The problem is that I cannot even see any error, the request is just pending forever. What's interesting is that if I split the content onto two different fields that won't help either. This tells me that it may be the Content-Lenght issue or something.

Expected Behavior: The document should save successfully, even with large amounts of text in the fields.

Actual Behavior: The save request remains pending indefinitely and the document is not saved.

Environment: MacOS, GCP, Docker, MongoDB

Thanks in advance for any help!

Reproduction Steps

For me it's quite easy to reproduce the issue. It happens on every payload instance I have tried so far. The collection schema may be for example:

const MySchema = {
  slug: 'myschema',
  fields: [
    {
      name: 'largeTextField',
      type: 'textarea',
    },
    // other fields
  ],
};

Now if I populate the largeTextField with a significant amount of text (e.g., 20k of text data) the form will not be saved
