Apologies for the delay! We used a slightly different implementation since that initial time we weren’t able to get it work with the previous instructions. It seems to be working well but we’ve had to increase the timeout up to 20 seconds (from 3s and then 10s) because we were still hitting 502 Errors - “ERROR: Bad gateway - the service failed to handle your request”
We’re going to also add in a initial HTTP Request (with the original node) attempt and then pass it to Lambda Node if it fails.
Good news is on the past 18 runs, we haven’t had a single HTTP Request failure so this seems to have done the trick.
Appreciate all the hard work on this. And the offering to help implement it too! You’re a hero
