event.detail is undefined in Lightning:recordEditForm submit event

Question

I'm trying to get field values at Lightning:recordEditForm onSubmit() event.In the documentation example it shows below.

my onSubmit event handler as below,

I end up getting error,

[event.detail is undefined]

Not too sure why I'm getting this error, I hope it's correct as per documentation.

Question: Why do I get this error, seems not a spelling mistake?

Also wondering where to find any documentation on what's available in Lightning:recordEditForm onSubmit event's parameters? Lightning component Library Documentation seems not covering much information this regard.

Appreciate any help, suggestions on this. Cheers!

Reference documentation is incorrect; i.e.: of lightning web component: lightning-record-edit-form, where to access the data we use:

console.log('fields: ' + JSON.stringify(event.detail.fields));

And in your example, you are working with lightning aura component: lightning:recordEditForm, here the syntax is:

console.log('fields: ' + JSON.stringify(event.getParam('fields')));
