HTTP 400 error "Invalid 'response_format.json_schema.name'" when generic type is used for ResponseFormat #9416
Description
Describe the bug
OpenAI API fails with error if generic type is used for ResponseFormat:
HTTP 400 (invalid_request_error: invalid_value)
Parameter: response_format.json_schema.nameInvalid 'response_format.json_schema.name': string does not match pattern. Expected a string that matches the pattern '^[a-zA-Z0-9_-]+$'.
To Reproduce
Use any generic type as ResponseFormat. For example:
public class Cart<T>
{
public decimal Total { get; set; }
public List<T> LineItems { get; set; }
}
public class LineItem
{
public class ProductName { get; set; }
public int Quantity { get; set; }
}Expected behavior
This issue is caused by use of GetType().Name at
which results into
Cart`1 json schema name with ` symbol, while OpenAI API allows only alphanumberic values and _ or - symbols.
