Problem with "Suggest meeting slots using AI " template

Questions

Hi,
I am just a newbie at N8N and i wanted to test the above template.
Yet it does not work :
the workflow tool does not export any data to the “execute workflow trigger”
In the output of the workflow tool, it is written “Cannot read properties of null (reading ‘saveDataErrorExecution’)”

{
“errorMessage”: “Cannot read properties of null (reading ‘saveDataErrorExecution’)”,
“errorDetails”: {},
“n8nDetails”: {
“time”: “27/02/2025 08:23:08”,
“n8nVersion”: “1.80.3 (Cloud)”,
“binaryDataMode”: “filesystem”,
“cause”: {}
}
}

You didn’t share the workflow, please paste the json of the workflow inside a preformatted text block.

Do you have ideas about the problem ?

Oh this maybe an issue with webhooks and importing workflows. I’m not sure if it is an official issue but many time when importing a workflow with webhooks I find they will not work all the time, so sometime copy/pasting the node and deleting the node is required. Also make sure the workflow is set to active.

workflow is active and did not import : I create step after step.

Hi @G3M

How are you calling the subworkflow? What’s your nodes configuration? It would help a lot, if you could share your actual workflow(s) to see what you’re doing exactly.

Tip for sharing your workflow in the forum

Pasting your n8n workflow

Ensure to copy your n8n workflow and paste it in the code block, that is in between the pairs of triple backticks, which also could be achieved by clicking </> (preformatted text) in the editor and pasting in your workflow.

```
<your workflow>
```

Make sure that you’ve removed any sensitive information from your workflow and include dummy data or pinned data as much as you can!

Thanks! :raised_hands:
