Geckoboard shows invalid type provided: expected "float64", got "string"

Question

I am using Geckoboard to display certain metrics. I have used the Java API which to push my content to widgets in Geckoboard. However, when I try to push my data to Text widget I keep on getting the error as invalid type provided: expected "float64", got "string". There isn't much information available on the web regarding this. How would I remove the errors. Here is the link to my dashboard and the first widget is the error.
