Notion Module Error: Invalid Email Address in Parameter ‘uyX%3F’

Problem Summary

I’m getting a validation error when trying to create a database item in Notion from Google Sheets data. Both the legacy and new Notion modules are failing with the same error.

Error Message

Error
Validation failed for 1 parameter(s).
* - Invalid email address in parameter 'uyX%3F'.

Setup Details

  • Trigger: Google Sheets - Watch New Rows

  • Action: Notion - Create a Database Item

What I’ve Tried

  1. :white_check_mark: Verified the email from Google Sheets is valid

  2. :white_check_mark: Tried both the legacy “Create a Database Item (Legacy)” module

  3. :white_check_mark: Tried the new “Create a Database Item” module

  4. :white_check_mark: Confirmed the Database ID is correct

  5. :cross_mark: Both modules produce the same error

Questions

  • What does the parameter name 'uyX%3F' mean? (The %3F appears to be URL-encoded ?)

  • Could this be related to a Person/Assignee field in my Notion database?

  • Has anyone else encountered this specific error with Notion integrations? How did you fix it?

Additional Context

The Google Sheets module successfully retrieves data with no issues. The error only occurs when trying to write to Notion.

Any help would be greatly appreciated! :folded_hands:

Hi Morgan, the error suggests the email address mapped in the Notion module for that Google Sheets row is not valid. Here is what I would check:

  1. The email address in the Google Sheet for the row processed in the screenshot run

  2. That the mapping in the Notion module (for the email property) is correct (i.e., it’s the correct column from the Google Sheet)
