Hi - I am trying to find a simple way to collect a gmail thread id from either of 2 gmail triggers in a separate node to then use that thread id later in my workflow.
With multiple gmail triggers, when I am only interested in one of them firing at a time, I can’t refer back to the thread id in the original trigger node because if that specific account didn’t fire, the thread id isn’t available and I get an error.
I have tried Merge node, If, Switch…nothing works and I am tearing my hair out with frustration. Even custom JS code node. Each time whatever happens EACH trigger input runs vs EITHER.
Any ideas? Basically I just need an either/or node which passes through the thread id of whichever Gmail trigger fired, but doesn’t wait for both. It’s that simple.
Thanks in advance for any support!
