could you plz help me in this issue

Answer 1

Well, you didn't post your code, so it's hard to be sure, but you're doing a PUT to "https://storage.googleapis.com/persistentstoragebucket/?upload_id=...". "persistantstoragebucket" is a bucket name, but there should be an object name after that. With just the bucket name, it looks like a bucket creation request, which requires a project ID (thus your error).
Are you perhaps not specifying the name of the object you're trying to upload?
