Programmatically uploading (geo)JSON files throws mimetype error

[stefgootzen]

Bug Report

Calling this:

const filePath = '[...]/filename.geojson';

await payload.create({
    collection: 'geofiles',
    filePath: tmpFilePath,
    data: {}
  });

results in the following error:

TypeError: Cannot read properties of undefined (reading 'mime')
    at getFileByPath ([...]/node_modules/payload/src/uploads/getFileByPath.ts:16:34)
    at async createLocal ([...]/node_modules/payload/src/collections/operations/local/create.ts:65:21)

I'm using Payload 1.6.6.

Possible cause

I believe the problem lies in the the following code const mimetype = fromFile(filePath); (link) which ultimately in the file-type package does this new FileTypeParser().parse(tokenizer);.

FileTypeParser.parse() (link) does not support (geo)JSON.

The file-type states This package is for detecting binary-based file formats, not text-based formats like .txt, .csv, .svg, etc., does this mean that the payload upload system also only supports binary-based file formats?

Hey @stefgootzen this is very interesting. I have never run into this myself but I can see how this package would definitely cause some issues with text-based files.

We can likely swap out this dependency to support text-based files. I will convert this to a Discussion and then add it to our Roadmap.

If you'd like to help here, we would happily accept a PR. Looks like the package is only used in 3 places within our code so if we can find a suitable replacement, we can certainly swap it out.

Otherwise, we should be able to get to this in our Roadmap Priority 2 (next quarter).

Confirm it, I also encounter this error when uploading csv file via local api.
Any possible solution for now?

Try reading the file first, something like this:

import fs from "fs";

const tmpFilePath = 'filePathHere'
const fileBuffer = fs.readFileSync(tmpFilePath);

const geojson = await payload.create({
  collection: 'geofiles',
  file: {
    data: fileBuffer,
    mimetype: 'application/geo+json',
    name: filename,
    size: fileBuffer.byteLength
  },
  data: {}
});
return geojson.id;
