Loose string schema
Have you tried type.enum("'literal'", "'or'", "'any'", "string")?

Maybe type("string").as<Thing>()?

How to use reject correctly?
You should remove message from your ctx.rejectbtw. message in general shouldn't be used unless absolutely necessary. Something like
return ctx.reject({
    expected: "a total file size of less than 4MB",
    actual: `${(data.size/1024/1024).toFixed(2)}MB`
)}
return ctx.reject({
    expected: "a total file size of less than 4MB",
    actual: `${(data.size/1024/1024).toFixed(2)}MB`
)}
will output an error along the lines of must be a total file size of less than 4MB (was 5.32MB)

Out of interest, what's the output with string[] > 1? Because technically there it is guaranteed to be string. Although I can see it not being worth the cost to implement the logic
