UnexpectedEof at MultipartReader.nextPart

[spawnia]

Using the middleware works fine when running Deno straight from Source:

deno run --allow-net --allow-run --allow-read --allow-write --allow-env --unstable server/serve.ts

For production, i attempted to create a bundle and then run the server through that:

deno bundle --unstable server/serve.ts > serve.js
deno run --allow-net --allow-run --allow-read --allow-write --allow-env --unstable serve.js

Now, when sending a POST request with an upload, the application responds with Internal Server Error. I was able to track down the error to

Upload-middleware-for-Oak-Deno-framework/mod.ts

const form = await mr.readForm(0);
