So I enter userID for the name, string for data type and Help with {{$$uuid()}} for the value but it keeps showing red text

What is the error message (if any)?

the error message is [undefined], i have tried asking meta and gemini and they both dont know too

Hi @Loggo_Voitto Welcome to n8n :n8n: community :tada:

Could you please specify the path of your uuid?

If it’s located in the root, you can reference it like this:

{{ $json.uuid }}

If it’s under body.data, you can reference it like this:

{{ $json.body.data.uuid }}

Alternatively, you can simply drag and drop the field from the left tab into the input field.

Let me know if you need any further assistance.

It looks like you’re trying to generate a new UUID and I dont believe $uuid() is a valid built-in function, so it’s best to use the crypto node like this:

Does crypto node help me to generate unique id for my next google sheet node. So i need userid for each different user with all their properties for the google sheet node.

Will the crypto node help me to achieve this?

Thank you

It’s a node for basic cryptography. You can use it to generate random string using one of the options. You can click the “Docs” button at the top right to get to the documentation, but best is to just play around with it. For example you could also just generate a fixed length random alpha numeric string using the Hex type:

Hi Wouter,

Thanks for your help. Yes I already integrated crypto node for my project. Though I am not stuck with other problem :slight_smile: I will try to find the solution myself before asking again. Thanks again for your help. Much appreciated.
