Invalid format: Input does not match the required pattern. Please ensure it adheres to the allowed character set and length constraints.

The error you are encountering, 'Browse graph' does not match '^[a-zA-Z0-9_-]{1,64}$' - 'tools.0.function.name', indicates that the name of the function or tool you are trying to use does not comply with the expected format specified by the OpenAI API.

Specifically, the error message suggests that the name "Browse graph" contains characters (in this case, a space) that are not allowed according to the regex pattern ^[a-zA-Z0-9_-]{1,64}$. This pattern only permits letters (both uppercase and lowercase), numbers, underscores, and hyphens, and the name must be between 1 and 64 characters long. The presence of a space in "Browse graph" violates this requirement.
