What is the current behavior?

Issue Number: #13931

I checked the report that some of the code to resolve the issue in the past was missing. To solve this problem, I modified RQM_DEFAULT_QUEUE.

What is the new behavior?

AS-IS

// packages/microservices/constants.ts
export const RQM_DEFAULT_QUEUE = 'default';

TO-BE

// packages/microservices/constants.ts
export const RQM_DEFAULT_QUEUE = '';

Setting this to an empty string enables the use of the default automatically generated queue name.

Does this PR introduce a breaking change?

• Yes
• No
