Uploads fails using S3_UPLOADS_USE_LOCAL

[garubi]

S3-Uploads ver 3.0.4 installed using manual-install.zip

I'm in local development (using Local by Flywheel 6.4.1, Ngnix, Php 8.0.0 on Windows )

I added in wp-config.php the row define( 'S3_UPLOADS_USE_LOCAL', "true" );

The uploads fail with the error: Unable to create directory uploads/2022/07. Is its parent directory writable by the server?

I verified to have allow_url_fopen = On

Being on Windows it's unlikely that's really a permission issue... Maybe the local wrapper fails?

Tryed also with WP-CLI wp s3-uploads verify

but failed with a fatal error:

Note that your configuration should be

define( 'S3_UPLOADS_USE_LOCAL', true );

(No quotes around the true value.)

fopen('', 'wb') seems suspicious, and would indicate you're hitting this conditional:

https://github.com/humanmade/S3-Uploads/blob/cafb1d4436c65f12c722ff0e8a900ca8b1bbd683/inc/class-local-stream-wrapper.php#L148-L152

That is, I suspect realpath() is returning false as your upload directory potentially doesn't exist or can't be created.

My guess would be that this is a permissions issue with PHP not being able to write to either the uploads directory, or create the subdirectory within it.

@rmccue thanks for your reply.

I corrected this: define( 'S3_UPLOADS_USE_LOCAL', true ); don't know why I put it in quotes, but this doesn't changed the problem.

I performed some more checks and I discovered that the wrapper can successfully create the uploads folders and subfolders, but it can't upload/write the files: the folders are empty.

About your suggestion that realpath() fails I think I can confirm it: in debug.log I have:
