Seeing these warnings on tempalates with file grids inside fluid fields - just file + alt text on this occasion. All fine both front and back end apart from warnings. Image paths are good. File browsing is fine. Saving OK too.

EE 7.2.17 + PHP 8.2 (also tried 8.1).

Do fields with ID 1 and 26 actually exist? If yes, what are the field types?

Hi Yurl

Yes - both of them are file grids (warning appears when used inside fluid fields in template). They exist in and are being used (and rendering data to templates)
