I have configured React to send an email when I receive data to my channel. My channel recieves data occasionally from an Android app, once every 15 minutes for the space of some hours.
Usually this works fine, but occasionally I do not recieve an email. I see that the app sent the data to the channel correctly and received a reply. The React shows that the code sending the email was run without errors (showing the green checkmark and showing last run 1 minute ago). As it was 15 minutes since the last request, it shouldn't cause the 429 error (too many requests). How can I find what the problem was? The email was not received.
