@carlos94587 the issue is that everyones specific error is different. So there is no universal solution that says “do this and it’ll fix your problem” unfortunately 
To work around this successfully you have to understand what that error is “trying” to say, since, well… the message is not descriptive in any sort of helpful way (Zapier should work harder at providing more ‘clues’ for individual use-cases).
What’s it’s trying to say is that a field you are sending to the CMS is wrong.
Maybe the field in the CMS is required and you’re sending something blank. Maybe the field no longer exists. Maybe the field expects a number and not a string of data. Maybe you’ve updated the CMS (and may not even remember) and now Zapier is out sync. Maybe… <insert 100 other possible reasons why>.
They key to solving it is to chip away, one by one, at all the possibilities until you start to get some clarity as to what the true problem is.
That was the basic exercise that @BrownHFX and I went through (over email).
I recommended for him to do “something” that then in turn showed what the true problem was.
If you have the time, and willingness - I know it’s super frustrating and it feels like you shouldn’t have to waste your time on this when you pay for services. But, this is the reality of us pushing beyond the limits, to make awesome stuff 
If you have the time, and willingness…look at the problem from this perspective. Try adjusting Zapier. Try refreshing the fields in Zapier (it connects to your CMS to fetch the most recent fields). Create another Zapier zap and only attempt this with 1 field to get it to work. When it does, add a 2nd field. Do this one-by-one until it breaks.
One thing I like to do, but is super technical, is to ping the Webflow CMS directly as if I were Zapier. How? If you look at the Webflow CMS API docs, on the right hand side you’ll see a curl
statement if you’ve selected shell
(versus javascript
) for the example request.
Figure out how to use curl
through some Googling if you don’t already know…try to make a curl
call directly into your CMS with the fields and values Zapier is sending. Go back to my previous statement and instead of doing all of them, start with just one field and one value. Get that to work. Add another, and so on…
Major PITA, I know… but if you take the time to go through this process, chances are you’ll come out learning a ton that will help you in the future, and have a high likelihood of solving your problem today.
Now that was a long arse post!
Hopefully you can pull 1 or 2 tidbits out of it that’ll help you!
