Getting an error on using "Call n8n Workflow Tool"

Describe the problem/error/question I have created a workflow in which I use “AI Agent” and through that I use the “Call n8n Workflow tool” to call another workflow. Each time I run the workflow I get the below error

{
“errorMessage”: “The workflow has issues and cannot be executed for that reason. Please fix them first.”,
“errorDetails”: {},
“n8nDetails”: {
“time”: “2/5/2025, 12:21:05 AM”,
“n8nVersion”: “1.76.1 (Cloud)”,
“binaryDataMode”: “filesystem”,
“cause”: {}
}
}

Can someone help with what the error might be?

Hey hi,
I also got the same error when using node “call n8n work flow tool”

I’m do a simple workflow with AI Agent, in which I use the “Call n8n workflow tool” node, and I get the error “The workflow has issues and cannot be executed for that reason. Please fix them first.” when running this node! I installed self-host n8n on digital ocean, and I also get the same error when self-hosting on render.

This is error log:

  • n8n version: 1.76.3 (self host)
  • Database (default: SQLite):
  • n8n EXECUTIONS_PROCESS setting (default: own, main):
  • Running n8n via (Docker, npm, n8n cloud, desktop app): docker
  • Operating system:

I hope to get support from the community also! Thanks!
