Running this code
pf = ParametricNDSolveValue[{y''[x] == -a y[x], y[0] == a,
y'[0] == b}, y, {x, 0, 20}, {a, b}];
ContourPlot[{pf[a, b][5] == 0}, {a, 0, 5}, {b, 0, 5}]

then copy and past this image to input cell. Execute the cell. The following message appears:

ParametricFunction::argrx: ParametricFunction called with 0 arguments; 6 arguments are expected. >>
