Error: no PRNG during generating Random scalar.

Hey Devs,

i'm facing 1 issue during generating Random Scalar. Here is a issue,

Error: no PRNG

    at Function.executeUserEntryPoint [as runMain] (node:internal/modules/run_main:79:12)
    at node:internal/main/run_main_module:17:47
    

code that generates err:

const ristretto255 = require('ristretto255');
const Scalar = ristretto255.scalar.getRandom();

anyone have a solution for this...
