Was there a recent change to how Slack’s “Send Channel Message” Thread Ts should be configured? Several of my Zaps started failing, despite me not making any changes to them.
My Zaps were configured with the following flow (screenshot 1), where “Follow up to message” would post into the original message’s thread. I configured this by selecting the original message’s Thread Ts as the value for Thread in the “Follow up to message” step (screenshot 2). This worked for several months, but started failing in the past month or so - at first only sometimes, but now consistently.
I was able to fix this for now by updating the Thread to use the original message’s Ts instead of Thread Ts (screenshot 3). It seems like there was a backwards incompatible change here. Is this a known issue?
