please have you an idea

It is quite possiblle that a npm module you are using is expecting an array which it tries to spread but it gets undefined or something non-iterable instead. Try and check what part of your application uses that module and where it may pass a non-iterable value where it would expect an iterable one. — Talmacel Marian Silviu, Mar 27 '21 at 23:21

It's not possible to see exactly reason, but It happens when you try to assign some variable (object/array) use spread syntax but the value is primitive data type.

for example:

let x = []
let y = 1;

x = [...y]
