input_validation_error
Function name does not conform to the required pattern: Only letters, numbers, underscores, or hyphens are allowed, with a maximum length of 64 characters.
This error has been identified and solved.
Reason
The error "multi_tool_use.parallel does not match ^[a-zA-Z0-9_-]{1,64}$" in the OpenAI API is occurring because the model is attempting to invoke a tool named multi_tool_use.parallel, which does not conform to the valid naming pattern expected by the API.
Here are the key points:
The model sometimes hallucinates or generates tool calls that include invalid characters, such as dots, which are not allowed in tool names according to the API's validation rules.
The specific tool name
multi_tool_use.parallelis not a valid tool name as per the API's naming conventions, which require tool names to match the pattern^[a-zA-Z0-9_-]{1,64}$(i.e., only letters, numbers, underscores, and hyphens are allowed).This issue arises because the model may generate nested tool calls that the API layer does not handle correctly, leading to the generation of invalid tool names.
Solution
To fix the 400 status error due to an invalid function name in the OpenAI API, you need to ensure that the tool names conform to the required pattern. Here are the steps to correct this:
Rename the tool: Change the tool name
multi_tool_use.parallelto a name that only includes letters, numbers, underscores, or hyphens, and is no longer than 64 characters.Remove invalid characters: Eliminate any dots or other invalid characters from the tool name.
Use valid characters: Ensure the new name only uses letters (a-zA-Z), numbers (0-9), underscores (_), or hyphens (-).
By adhering to these guidelines, you can avoid the validation error and successfully invoke the tool.
