Airtable Queries & Parameters not working

Hi,
Anyone tried lately the queries with Airtable. I have followed the following Topic: Query Parameter with Airtable - #8 by sriramganesh

But My queries not working in any shape whatsoever. Thank you.

The most common error here is that there is a space in the query. Please double check to make sure there are no extra " " (spaces) in your queries.

Hi Colin,
No spaces, I have the same behavior as in that topic. Some times it works, some times does not work.
