Hi @utahbikerdude
I recommend opening a ticket with Zapier Support to look into this error further: https://zapier.com/app/get-help
Hi there, @utahbikerdude 
I just came across this and saw that the Support team added you to a bug report where Send Channel Message and Send Private Channel Message Slack actions (with a file attachment selected) were returning “Error while hydrating data from Slack: Cannot convert undefined or null to object” errors. Looking at the bug report though I can see that the issue was since resolved! 
Not sure if you’ve seen the email notification that was sent out yet, but I wanted to confirm that no changes to your Zaps are needed to get things working again.
That said, if you run into any further issues do let us know. In the meantime, happy Zapping!

I just received the same hydrate error from a run 15 minutes ago….
I’m so sorry to hear that, @utahbikerdude! In that case I’d suggest reaching back out to the Support team to flag that the issue appears to have resurfaced. They’ll investigate further and can re-open the bug report or create a new one if needed..
Want to make sure this gets taken care of, so please keep us updated on how you get on with them!
