This message is generated when the argument in (RefLink[Root, paclet:ref/Root]) is not a polynomial in the indicated variable.

(RefLink[Off, paclet:ref/Off])[message] switches off the message; (RefLink[On, paclet:ref/On])[message] switches it on. For example: (RefLink[Off, paclet:ref/Off])[Root::npoly].

The (RefLink[Root, paclet:ref/Root]) function is intended only for use with univariate polynomials (expressions with a single variable and integer exponents):

Root[2-Sqrt[x],1]

The root of this expression can be computed using (RefLink[Solve, paclet:ref/Solve]):

Solve[2-Sqrt[x]==0,x]
