Deleting files with UTApi, unauthorized

Hey, I'm trying to delete a recently uploaded file when the form is closed but I'm running into auth errors, please can someone help me to understand what I'm missing with the setup - screenshots attached

onUploadComplete stores the file url in the form (and updates the useState to trigger a refresh)

1st ss: trpc mutation
2nd ss: onClose fn for form close
3rd ss: upload component
