General::stop: Further output of ParametricNDSolveValue::ndsz will be suppressed during this calculation

How to overcome this error?

ode = D[theta[x], {x, 2}] == SH*theta[x]^2 sol = ParametricNDSolveValue[{ode, theta[0] == 1, theta'[1] == 0}, theta[x], {x, 0, 1}, {SH}] Ns[SH_, Tr_] := SH*sol[SH]*(Log[1 + Tr*sol[SH]] - sol[SH]/(sol[SH] + (Tr - 1)^(-1))) Plot[Ns[10, 1.2], {x, 0, 1}]
