Nodejs sharp error - Input file contains unsupported image format might be a race condition

Was doing some S3 work where I had [TODO: Code shorthand span ] that worked locally but not on the server.

Realized that it was causing a race condition with sharp.

Fix was to flip over to using [TODO: Code shorthand span ] so the process didn't move on until the file was finished writing
