Upserting file - cant create signed URL if file already exists?

Hey all,

So im trying to generate a signed URL to upload a file (I basically want to replace the existing one so I am creating a signed URL to the file I want to replace.

This gives me an error message. (Image attached is what im doing)

However, then I see there is a second method which allows me to 'upsert' to a signed URL?

Might be obvious but the question is how would I upload/upsert to a signedURL for a filepath when I cant even create the signed URL in the first place?

Maybe im missing something obvious
