Having issues with SQS and Localstack? Try upgrading the Localstack version

[debora-ito]

In the Java SDK version 1.12.585, the SQS model changed its protocol from Query to JSON.

If you are using Localstack with SQS, you might start to see errors after upgrading the Java SDK to a version >= 1.12.585, errors like Unexpected character ('<' (code 60) or AmazonSQSException: null (Service: AmazonSQS; Status Code: 500...)

Localstack needed to accommodate the protocol change on their side, so you need to use a Localstack version compatible with the change. Here's the tracking issue in their github repo - localstack/localstack#8267 (comment).

How to fix

To avoid this issue, you need to:

• use a Localstack version compatible with the protocol change (like localstack/localstack:latest)
  OR
• pin the Java SDK version to <= 1.12.584.
