I'm working on a project to upload images to google cloud storage. I've tried many methods but vercel says it can't find the json file that is the key for connecting to google cloud storage. But when I try using it myself ngrok that is used to run on the machine can send images to save in google cloud storage, but when uploading to vercel, I get the message as mentioned in the first episode. Who knows or has done it before? Please reply to me. Thank you.
