Strange error message

I got this error message in my log
2016-04-08 15:49:41 UTC-4 [Agent] ERROR: Read: JSON Error:
2016-04-08 15:49:53 UTC-4 [Agent] ERROR: the index ‘code’ does not exist

I’m working with firebase, but i dont have “code” anywhere…I just dont get it

I think the error is being raised by this line in our firebase library.

That’s not the latest version of the library. Try modifying your #require line to match the latest one on the web services page. Does that fix it?
