TypeError: source.visitorKeys[node.type] is not iterable

eslint-plugin-unicorn@25.0.0

prefer-default-parameters.js:36:38

by code:

const length = quantity || 0;

@yoyo837 Thanks. I did some debugging and noticed that this issue was actually caused by the following line:

const { genMode, quantity, seatUnit, rowsName, seatName, startFrom, ...restData } = formData;

It seems like ESLint considers the ...restData to be an ExperimentalRestProperty, which doesn’t have a corresponding entry in the visitorKeys map. I’ve fixed the issue by checking for undefined keys before iterating over them.
