I have a weird issue where a call to pwg.images.addSimple fails when the image in question is added with the tags parameter present.

Piwigo is 14.1.0
Apache2 2.4.57-2
php 8.2

on Debian Bookworm.

I am pretty sure this used to work, but since I upgraded Piwigo and PHP I cannot tell you which of the two might have broken it.
There is of course also a small chance that I am doing something weird in Shotwell's upload code.

Failure mode is either a 501 Missing "method" name if the tags are hierarchical (eg. "/foo/bar/baz") or a 401 Access denied if its just plain tags.

Working form data:

Its a bit weirder. If the first thing you upload has the second post format, only then another post with "normal tags" included will fail - even if it worked before

Ok, this is probably not a bug but a config issue, trying to upload files that exceed upload_max_filesize/post_max_size - a nicer error message would be helpful, though

Appear to have resolved the max_filesize issue?

So, this is not a tags problem at all?

Maybe. But there is definitely different behavior depending on the type of tag there, which is also weird

I'm testing with nginx instead of apache but on Debian 12 as well. It works fine but I indeed have to adjust /etc/php/8.2/fpm/php.ini to increase values for post_max_size and upload_max_filesize
