Graphql video upload

Hi there, I am using the

mutation stagedUploadsCreate in order to upload a video file (25mbs) and post it in my client’s shopify store. I successfuly get the policy, key, signature, googleaccessid and the url [https://shopify-video-production-core-originals.storage.googleapis.com?external_video_id=[Video](https://shopify-video-production-core-originals.storage.googleapis.com?external_video_id=[Video) ID] but whenever I try to send a post (or even a put request) in postman I receive this error even though I also have set the header of “X-Shopify-Access-Token”

I have tried sending both a post and put request to https://shopify-video-production-core-originals.storage.googleapis.com?external_video_id=[videoid] or even https://shopify-video-production-core-originals.storage.googleapis.com

Also I have tried setting the content-type to application/graphql to no avail (it should be normally set as multipart/form-data since I am uploading a form

I am having this identical issue. Images upload successfully but videos result in the missing header above. Was this ever resolved?
