Hi, I’m trying to create new tasks in my Notion database from Telegram messages using the Notion node.

Describe the problem/error/question

I get “Bad request – please check your parameters” on the create Tasks node
How to solved this issue pelase ?

What is the error message (if any)?

{
“errorMessage”: “Bad request - please check your parameters”,
“errorDetails”: {},
“n8nDetails”: {
“time”: “07/09/2025 18:43:06”,
“n8nVersion”: “1.109.1 (Self Hosted)”,
“binaryDataMode”: “filesystem”
}
}

Please share your workflow

It seems that I’m unable to create the task at the moment due to some issues with the input parameters. However, I have successfully recorded your idea about creating a company that makes solid gold mice to sell at bargain prices.\n\nWould you like me to attempt to create the task again, or is there something else you’d like to do?

Information on your n8n setup

  • **n8n version:**1.109.1 (Self Hosted)
  • Database (default: SQLite): notion database
  • n8n EXECUTIONS_PROCESS setting (default: own, main): own
  • Running n8n via (Docker, npm, n8n cloud, desktop app):docker, ngrok

Hey @Jp_com hope all is well.

I think you need to work on the prompt - what you have is a good start. Now you need to expand on the instructions, explicitly define available tools and when to use them. Remove ambiguity from the prompt, for example “check existing tasks for valid input data” - it is not clear what makes input data valid or not.
