missing_parameter_error
A required parameter is missing in the input. Please ensure that all necessary fields are included.
This error has been identified and solved.
Reason
The error Missing required parameter: 'messages.tool_calls.type' in the OpenAI API is likely due to several possible reasons:
Incorrect Message Sequence
The error can occur if the sequence of messages is not maintained correctly. Specifically, messages with the role 'tool' must be a response to a preceding message with 'tool_calls'.
Missing or Incorrect Type Specification
The API requires that each message and tool call has a specified type. If the type is missing or incorrectly specified, it can lead to this error.
Persistent Chat Store Issues
Loading the chat store from a persistent storage and reusing it can sometimes lead to errors if the messages are not correctly validated and maintained in the sequence expected by the API.
Solution
To resolve the Missing required parameter: 'messages.tool_calls.type' error in the OpenAI API, you need to ensure the following:
Correct Message Sequence: Ensure that messages with the role 'tool' are responses to preceding messages with 'tool_calls'.
Proper Type Specification: Verify that each message and tool call has the correct type specified.
Validate Chat Store: When loading the chat store from persistent storage, make sure to validate and correct the messages to maintain the expected sequence.
Additionally, check for any inconsistencies in the message structure and ensure all required parameters are included.
