Format Validation Error for tools[12].name in ChatGPT 5.2 Conversations #7777
Description
Description
When using ChatGPT 5.2 for conversations, a format validation error is triggered for the tools[12].name field: Invalid 'tools[12].name': string does not match pattern. Expected a string that matches the pattern '^[a-zA-Z0-9_-]+$'. However, the same tool configuration works without errors when switching to other models (those with this validation rule disabled).
