Slack retry header issue

[amitza]

Hi,

In this example under the slack_bot lambda, the following code handles slack retry messages:

Multi-Interface-Chatbot-using-Amazon-Q-and-Slack-with-CloudFront-Clickable-References/lambdas/slack_bot/index.py

Lines 45 to 50 in 50d6f6e

	if 'x-slack-retry-num' in event['headers']:
	slk_retry = event['headers']['x-slack-retry-num']
	logger.info({"slk_retry": slk_retry})
	metrics.add_metric(
	name="Retry",
	unit=MetricUnit.Count,

However when deploying this example the actual header returned from slack is: X-Slack-Retry-Num and not x-slack-retry-num.

example from lambda event log:

"headers": {
            "Content-Length": "865",
            "Content-Type": "application/json",
            "User-Agent": "Slackbot 1.0 (+https://api.slack.com/robots)",
            "X-Forwarded-For": "3.89.205.0",
            "X-Forwarded-Port": "443",
            "X-Forwarded-Proto": "https",
            "X-Slack-Request-Timestamp": "1739205646",
            "X-Slack-Retry-Num": "1",
            "X-Slack-Retry-Reason": "http_timeout",
            "accept": "*/*",
            "accept-encoding": "gzip,deflate"
        },

the official slack documentation also reference the header as x-slack-retry-num so I'm not sure, maybe I got something wrong.
