[FIXED] Failed to load object with presigned url Minio Python

Issue

i'm using Minio Server to handle files in my Flask API. I generate Presigned Url to upload images directly from Angular FrontEnd to save Backend resources.

Presign Url Generation works fine but when I upload my file from Postman or Angular Code, the file seems corrupted.

Same on the Minio web browser

I use simple code for presigned url generation :

    def get_presigned_get_url(self, bucket: str, object_path: str) -> str:
    url = self.client.presigned_get_object(
        bucket_name=bucket,
        object_name=object_path,
    )
    return url

def get_presigned_put_url(self, bucket: str, object_path: str) -> str:
    url = self.client.presigned_put_object(
        bucket_name=bucket,
        object_name=object_path,
    )
    return url

And PUT request on Postman

Thanks for your help

Solution

The key in this case is how the file is uploaded from the postman. While uploading the file, you need to use Body > Binary > Select File, rather than using the Body > Form-Data.
