An error occurred (404) when calling the HeadObject operation: Not Found:

I had the same issue recently. You are probably misspelling the path and folder name. In my case, for example, I was messing up with the ‘/’.

To fix it, make sure the variables you are using as arguments for the function contains the correct names of the directories, folders and files as it is in S3. Also, make sure you put the ‘/’ in the correct places in the correct variables. For instance, in my case I found that:

• bucket name: bucket_name (with no ‘/’ in the end, and no ‘s3://’)
• directory name: folder1/folder2/file_name (with no ‘/’ in the beginning)

I hope it helps you and others to get around this error easily.
