Add temporary retry loop for 500 responses

[silvi-t]

Description

This PR updates the test to replace the 5-second sleep with a temporary retry loop that:

• Repeats requests until a 200 response is received or a maximum number of attempts is reached.
• Logs the elapsed time and number of requests.
• Serves as a temporary solution until the underlying issue causing 500 responses is resolved.

Notes:

• The loop is meant to be removed once the test passes consistently without retries.
