Receiving Invalid request signature detected

[manish001in]

Hey team, So, I am receiving the Invalid request signature detected. In last few days, it has become very common! I have made a change to my system where the event that I get is responded with ack() and then I use FastAPIs background tasks to run the business logic and processing for the message event.

Weirdly this does not happen for each event, only few events! In the background tasks, I use the event_context to call apps.event.authorizations.list api endpoint.

I am not sure why this issue is emerging. Does the event_context also expire?

Reproducible in:

The slack_bolt version

slack_bolt==1.20.1 slack_sdk==3.32.0

Python runtime version

Python 3.11.6

OS info

Amazon Linux release 2023.5.20240903 (Amazon Linux) #1 SMP Tue May 21 16:54:42 UTC 2024 (Paste the output of sw_vers && uname -v on macOS/Linux or ver on Windows OS)

Steps to reproduce:

Expected result:

I should not get intermittent issues with Invalid Request signature.

Actual result:

This is one log:
