CORS issue with L-ML/Minio/FilePond

[jayenne]

I have L-LM working a dream with filepond until I canged my storage to s3 / MinIO on my stack (TALL8 / Jetstream / Sail / MacOS) and now get CORS failure so nothing can upload.

(Reason: CORS request did not succeed).

I have tried cobinations of true/false for:
config/cors: 'supports_credentials' => true,
config/media-library: 'enable_vapor_uploads' => env('ENABLE_MEDIA_LIBRARY_VAPOR_UPLOADS', true),

*I don't know if either are required but it's as per some web posts.

• should enable_vapor_uploads be true or false for Livewire? (it only mentions Vue/React)
  *I don't know if MinIO buckets need some special CORS config but can't find anything about it on the web.

FYI: The seeder still "uploads" files perfectly so I'm sure the minio is installed and working too (maybe not fully?).

I'm sure it's just a config issues but am stumpped and can't find anything on google/laracasts of any help. Pointers to reseach, resolve or debug further would be hugely appreciated. thanks.
