I am using zod to parse payload we received from URLSearchParams, which requires transforming comma-separated string values into an array of string (which can potentially be empty/undefined). In v4.3.6 and below, the following schema works:
z.object({
area: z.preprocess(v => v ? v.toString().split(',') : [], z.array(z.string())).catch([])
})And the payload is as follow:
v4.3.6 on Zod Playground, which works without any issue ✅
However, after upgrading to 4.4.x (4.4.0, 4.4.1, and 4.4.2), I get the following error:
invalid_type - Invalid input: expected nonoptional, received undefined
All these versions are showing the same error:
