'{field}' array must only contain strings

Error message

'{field}' array must only contain strings

What it means

parse_string_list accepts a proxy list field ('no_proxy' etc.) as either a comma-separated string or an array; this fires when an array element is not a string (number, object, null). The {field} names which arguments key contained the bad element.

Solutions

1. Make every element of the array a string, e.g. ["provider.openai", "tool.http_request"]
2. Or pass a single comma-separated string instead of an array
