Assets not directly uploadable via assets field (without dynamic folder feature enabled)

[marcorieser]

Bug description

Happens since v5.27.0 (v5.26.0 works).

When there is an assets field (without special configuration) and I try to upload an asset directly inside an entry via drag/drop or by clicking the upload button, the following error shows.

However, uploading assets via the assets area and linking them in an entry is still possible. Also, the issue does not occur when I activate the new dynamic folder feature.

How to reproduce

Clone the repo:

• https://github.com/marcorieser/statamic-asset-upload-bug

Or:

• Install a new site
• Add an asset field to the page blueprint (no need to configure anything)
• Create a new page entry
• Try to upload an asset into the asset field
