cognitoidentityprovider initiate_auth with "USER_PASSWORD_AUTH" Errors when searching for additional credentials about paws HOT 5 CLOSED

I have found the bug. We accidentally removed all X-Amz-* headers when using anonymous. The dev branch should fix this.

remotes::install_github("dyfanjones/paws/paws.common", ref = "anonymous_cred")

library(paws)

svc <- cognitoidentityprovider(config(credentials(anonymous = T), region = "us-east-1"))

resp <- svc$initiate_auth(
  ClientId = "YOUR CLIENT ID",
  AuthFlow = "USER_PASSWORD_AUTH",
  AuthParameters = list(
    USERNAME = "YOUR USER NAME",
    PASSWORD = "YOUR PASSWORD"
  )
)

For extra context:
There is a slightly difference in how paws works compared to boto3 when getting credentials. Boto3 doesn't check if it has credentials where paws does (hence: Error: No compatible credentials provided.). I don't think we will remove this check as it is fairly useful and other aws sdk's do something similar.

Let me know if this fix works for you.

Have you tried with anonymous credentials?

Hi @DyfanJones, thanks for the reply!

I attempted to initialize the client with anonymous credentials according to documentation which suggests a logical value:

library(paws)
svc <- cognitoidentityprovider(
  credentials = list(anonymous=TRUE),
  region = "us-west-2"
)

svc$initiate_auth(
  ClientId = "<auth_client_id>",
  AuthFlow = "USER_PASSWORD_AUTH",
  AuthParameters = list(
    USERNAME = "<username>",
    PASSWORD = "<password>"
  )
)

This results in a "400 Bad Request" error, with the Amazon error type "Unknown Operation Exception".

Sorry about that, not sure what is going on. I will have to set up cognito to understand what is causing the issue.

Yes, this does the trick! Thank you for the solution and the clarification. Really appreciate your time.
