Most action apps will have required fields, which require you to select or enter data. If a required field is empty, your Zap will error.
Insert data from previous steps
One way you can send data to a required field is by mapping fields.
Check to see if data is always coming through from the previous step
Sometimes, when a Zap runs, you’ll still see an error message that a required field is missing, even though it's mapped to a field from a previous step.
Sometimes, this can occur if the trigger or previous action step doesn't always have a value. This can happen if the mapped field is optional. When possible, only map required fields to another required field.
Use a default value
You can use a Formatter step to add a default value as a fallback whenever your mapped fields don't send data.
Use Filters or Paths
If the error persists, contact Zapier support.
