Symptoms
When using Formatter in your Zap you see the error message “413 Request Entity Too Large”. You may see this error when setting up a Zap or in the details of a Zap run in your Zap history.
Causes
This happens when the data added in the Input field exceeds the maximum data size of 14 MB.
How to fix it
To fix this:
- Ensure the data sent to a Formatter step does not exceed 14 MB.
- If you know data over 14 MB will come through, use a Code by Zapier step to calculate the size of the data. You can use Javascript or Python.
- (Optional) You can also use the Code with AI feature to generate a script for you.
- Once the script is in place, add a filter to your Zap right after the Code step, to stop it running if the data exceeds the limit.
