creating a type based on the input

export function getType(cols: Column[] | undefined){
    if (!cols) return z.object({});
    const schema = {};
    cols.forEach((col) => {
        schema[col.id] = z.string();
    });
    return z.object(schema);
}

export function getType(cols: Column[] | undefined){
    if (!cols) return z.object({});
    const schema = {};
    cols.forEach((col) => {
        schema[col.id] = z.string();
    });
    return z.object(schema);
}

im getting this error on schema[col.id]

Element implicitly has an 'any' type because expression of type 'string' can't be used to index type '{}'.
  No index signature with a parameter of type 'string' was found on type '{}'.

You need to use the setKey method.

const schema = someData.reduce(
  (schema, definition) => schema.setKey(definition.name, z.string()),
  z.object({})
);
