Fix the exact error that stopped your work

A Make connection timeout means a module waited for the target service and got nothing back within Make's time limit — the target API is slow or down, a firewall or IP block is refusing Make's servers, the connection's authorization has gone stale, or the request is too large to finish in time. Check the target service first, re-authorize the connection, then shrink or split the request.

Notion's "Syntax error in formula" means the formula editor can't parse what you typed — a misspelled or wrongly-quoted property name, a missing comma between function arguments, unbalanced parentheses, a string that lost its double quotes, or the wrong operator. Read where the caret points, check that one spot against the six common causes, and fix it character by character rather than rewriting the whole formula.

A 400 on a Zapier webhook means the request that reached Zapier (or the app your Zap sends data to) was malformed — an invalid or empty JSON body, a missing or wrong Content-Type header, a bad hook URL, or a required field the receiving app rejected. Read the exact error body in Zap History, check the request the sender actually made, and fix the payload or headers to match.
