Missing value of required parameter 'title'. - Google Calendar > Notion -

Hi everyone,

I currently have a zcal scheduling account (alternative to Calendly check it out!) where people book a time and it creates a google calendar event.

What I am trying to create I believe should be quite simple, whenever a google calendar events get created I would like my notion “Calendar Appointments” database to be updated by creating row with relevant information.

However this is the error I get on the notion module

And I’m not sure if “title” within the error is referring to a specific field on the DB, because I haven’t got such a field on there

This is an example of the Calendar module with manual selection of 1 particular event

Where am I going wrong please?

Looks like you’ve mapped a variable containing an empty or null value to a required field.

If you need further assistance, please provide the following:

1. Screenshots of module fields and filters

Please share screenshots of relevant module fields and filters in question? It would really help other community members to see what you’re looking at.

You can upload images here using the Upload icon in the text editor:

2. Scenario blueprint

Please export the scenario blueprint file to allow others to view the mappings and settings. At the bottom of the scenario editor, you can click on the three dots to find the Export Blueprint menu item.

(Note: Exporting your scenario will not include private information or keys to your connections)

Uploading it here will look like this:

blueprint.json (12.3 KB)

3. And most importantly, Input/Output bundles

Please provide the input and output bundles of the modules by running the scenario (or get from the scenario History tab), then click the white speech bubble on the top-right of each module and select “Download input/output bundles”.


Save each bundle contents in your text editor as a bundle.txt file, and upload it here into this discussion thread.

Uploading them here will look like this:

module-1-input-bundle.txt (12.3 KB)
module-1-output-bundle.txt (12.3 KB)


If you are unable to upload files on this forum, alternatively you can paste the formatted bundles in this manner:

  • Either add three backticks ``` before and after the code, like this:

    input/output bundle content goes here

  • Or use the format code button in the editor:

Providing the input/output bundles will allow others to replicate what is going on in the scenario even if they do not use the external service.

Following these steps will allow others to assist you here. Thanks!

Hi @samliew

Thanks for your reply

See attached below

Output Bundle

output_bundle.txt (8.0 KB)

I didn’t get the input bundle because it was empty

You are mapping the first attendee’s displayName into the required field, which does not exist.

As you can see, the available variables for the first attendee are:

  • email
  • organizer
  • self
  • responseStatus

that’s very interesting, whilst I can see the same thing you are seeing within the bundle text, in the front end on make there’s actually an attendee display name variable that I can use

Tad confusing

Yes, the variable is there and selectable, but it’s empty.

Hi @samliew

Sorry maybe it’s me getting confused.

But since the variable is empty that’s why I initially selected the attendee display name as a value to use, which is what I’d like to track anyway.

But it seems that that’s causing also the issue the missing value parameter within the output text bundle, so how do I fix it?

Or am I missing something?
