Problem Creating Slack Channels from Notion CRM Data

Hello to the Make community,

I’m trying to automate the creation of Slack channels based on company names stored in my Notion CRM. The goal is simple: every time there is a new customer in Notion, a Slack channel should be created with the company name as the channel name.

Here’s what I’ve done so far:

I get the company name from Notion and use the lower() function to make sure the name is lowercase.

However, the slack module constantly returns an error. I’ve tried it with a value I’ve written and everything works fine. The error comes from the transmission of the text between notion and Slack.
In my CRM Notion, the company name is “bonjour” and it’s in the text version.

What could be the cause of this problem? Am I missing something in terms of data formatting, Slack rules or Make configuration?

I’d appreciate any help or insights from the community. Thanks in advance! :blush:

Here is a screen of my scenario:

Hello Milard,
What error message do you get?

hello, this

When reviewing the specific run that causes the error, do you see a value in the “Company name” property of the processed Notion page? You can check this by going to the History tab and clicking on the bubble icon next to the Notion module.


I have the link to the page, in this page there is the company name

Ah quite strange - here is what I would check:

  1. Expand “Properties value” in the screenshot above and check if “Company Name” (plain text) has a value
  2. After refreshing “Watch database items”, I would remap “Company name” in the Slack module to ensure it’s using the freshest, latest correct property
