'{field}' must be a string or string[]

Error message

'{field}' must be a string or string[]

What it means

parse_string_list only accepts a JSON string or an array of strings for the named field; the raw value was neither (e.g. a number, object, boolean, or an array containing non-strings after rejecting that case separately), so the proxy setting cannot be interpreted.

Solutions

1. Pass the field as a single string or as an array of strings
2. Ensure JSON numbers/booleans are quoted if they are meant as string values
