Report · Nov 08, 2022

I followed the instruction listed here, but when I try to upload the file with provided "uploadUri" I get this error:

Hi,

I can replicate the error if I change a character in the uploadUri or if I use another API request method.

So make sure you're making a PUT request to the correct uploadUri.

I'm running into the exact same problem. I just copy the URI from the POST asset API call, so I don't feel there's a mistake in the URL. @Developement27029123kd1u did you find the answer?

Can you share more of your code?

Report · Nov 17, 2022

-In Postman I create the asset through the /assets endpoint: https://pdf-services.adobe.io/assets
Response is a uploadUri and assetID
Then I do a PUT request to the uploadUri
- Authentication by parameters set in the received uploadUri

And then suddenly I saw my user mistake! In the PUT call the Content-Type didn't match with the content-type of the asset I created. Once I changed the content-type, the flow worked!

So my solution was to change the content-type in the PUT call to the Adobe storage service to match it to the content-type of the asset created in the /assets POST request.

ah, thanks for this! This was my mistake as well.

Hi,

It may also be related to the content of the body (file to upload) itself.

With Postman, when I try importing a file in a binary body it will work but if I try to copy the content of a file in a form-data body it will give me the same error as you even though there's no change in the signature of the request.

I'm still trying to make it work...

Same issue here. I've gotten data corrupted errors when using axios, so tried to debug using postman. Tried getting auth tokens for both east and west with the same result:

Ah, mine was the content-type as well. It's auto generated.
