The deprecated method appears to be files.upload. While that api will continue to function until March 2025, newly created apps (those of us adding the Slack integration now) can't use this method.

From the linked Slack page:

Existing apps & integrations should migrate away from files.upload and instead leverage a combination of two APIs: files.getUploadURLExternal and files.completeUploadExternal. The use of these two methods is more reliable, especially when uploading large files.

I currently have the same issue. First I had to add the "files:write" scope, then later I got the same error that this function is deprecated. Is there any workaround or fix I can use?
