Receiving Aws::S3::Errors::SignatureDoesNotMatch using Shrine lib

I’m trying to upload an attachment to Spaces by using Shrine lib from Ruby. here is my config:

s3_options = {
  credentials: Aws::Credentials.new("key",'secret'),
  endpoint: 'https://nyc3.digitaloceanspaces.com',
  region: "*",
  bucket: "*"
}

Shrine.storages = {
  cache: Shrine::Storage::S3.new(prefix: 'cache', upload_options: {acl: 'public-read'}, **s3_options),
  store: Shrine::Storage::S3.new(prefix: 'store', upload_options: {acl: 'public-read'}, **s3_options)
}

I’m trying to run following code:

attachment.attachment = File.open("data_test.jpg")

and receiving

Aws::S3::Errors::SignatureDoesNotMatch

what is necessary steps I should do to debug this issue, or probably there is knowledge base I haven’t located?

Thank you for any help!

hello @jankomarohnic - I have no idea what it was, I’ve regenerated access keys and it started working

Could the issue be that in the fact that you’re not opening the file in binary mode? That can cause issues sometimes, try opening it binary mode:

attachment.attachment = File.open("data_test.jpg", "rb")
