boto3 sqs incorrect url when not specified endpoint url

Do I always need to specify endpoint_url when creating boto3 client? Why can't I specify QueueUrl as method argument?

# boto3==1.16.51
import boto3


client = boto3.client('sqs')

messages = client.receive_message(
    QueueUrl='https://sqs.eu-central-1.amazonaws.com/325672072888/event-queue-test',
    WaitTimeSeconds=2,
    MaxNumberOfMessages=1,
    AttributeNames=["All"],
)

Exception:

botocore.exceptions.ClientError: An error occurred (InvalidAddress) when calling the ReceiveMessage operation: The address https://eu-central-1.queue.amazonaws.com/ is not valid for this endpoint.

Seems like it takes default values for sqs queue. But why it does not take value from QueueUrl

Solution

  • The url from the error msg is different then QueueUrl because AWS CLI and boto3 use legacy endpoint, one of which is eu-central-1.queue.amazonaws.com. From docs:

    If you use the AWS CLI or SDK for Python, you can use the following legacy endpoints.

    You can check this using:

    print(client._endpoint)
