ERROR! Failed to get presigned URLs about uploadthing

[Ngash01]

Filetype is set to blob and I tried uploading a PNG image. Not sure if this is a bug, or just wrong config on my end for localhost.

I actually had the exact same issue. If it occurs to you it's most probably due to a typo in your core.ts file. Mine was quite simple the maxFileCount object was set to a String instead of a Number. This is what I mean:
ImageUploader: f({image: {maxFileCount: "1"}}) Instead of ImageUploader: f({image: { maxFileCount: 1}})

I had the same error make sure you have your api exposed. And I was missing the environment variables: UPLOADTHING_SECRET and UPLOADTHING_APP_ID

This error disappears when I set the file permission to allow only images, and subsequently upload a PNG image file on localhost.

The moment I deployed to https://uploadtest-theta.vercel.app/ I got the same error.

blob requires content-type to be application/octet-stream -- this may be a bug, as the field should probably coerce all content-types to application/octet-stream

I'm getting a similar issue, I have a pretty basic setup and no file type limitations or size limitations. Not sure what this is about.

Here's my backend error

- error Error [TypeError]: resolver is not a function

@KyleMoran138 Can you share what your router definition looks like?

[t3dotgg]

Assuming this was missing env variables. Next release will have better errors for that. Re-open if you are able to provide a public repro

I get the same error when I want to upload a pdf, did you solve it?

Can you confirm which version of Uploadthing you are using, and share what your router config looks like?

Im facing the same issue. When I upload files that are present on the server everything works fine but when I try to upload files that are not on the server I get that nasty error and I dont know how to solve it.
