angularjs - how can i know what security firebase rule give me a error?

Question

I have this firebase security rule:

".validate": "newData.val().length < 2"

When the new data.length is > 2, Firebase returns a error that says "PERMISSON_DENIED".

I would like to know if there is a way to get a error info like this "the new data is to long".

Thanks
