Getting error if i change file name ExampleNode.node.js to TestNode.node.js

[Neeru_Olha]

I am trying to create a Custom node. It’s working when file name is ExampleNode.node.js this and if a change folder name, file name and class name then getting error :
TypeError: require(…).TestNode is not a constructor

It looks like your topic is missing some important information. Could you provide the following if applicable.

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

Hi @Neeru_Olha,

Welcome to the community

The error you’re seeing typically occurs when there’s a mismatch between how the module is exported and how it’s being imported. Here are a few things you can try out:

• Can you double-check that you’ve replaced ‘ExampleNode’ with your custom node name in all the required places?
• Can you check your package.json file and make sure it correctly references the node
• Can you try rebuilding & restarting your custom node and n8n?

It’s hard to troubleshoot without actually seeing the code though, could you maybe share more details about what you’ve done so far?

Hi @aya ,
This is how I’m writing the class:
export class TestNode implements INodeType {
description: INodeTypeDescription = {
displayName: ‘test Node’,
name: ‘testNode’,
}
}

I have updated the package.json file with the correct file path:
“nodes”: [
“dist/nodes/TestNode/TestNode.node.js”
]

However, despite rebuilding multiple times, I am still encountering the same error.
