Hi, I am aiming to use the new FlowBuilder's test messaging to test out the prompt I have built out. I ran into the initial error of: 401 Incorrect API key provided: sk-proj-********************************************************************************************************************************************************5qgA. You can find your API key at https://platform.openai.com/account/api-keys. I have created an API Key and added it to my WorkSpace that shows OpenAI is connected. Is this the issue? Right now, OpenAI no longer gives out the old-style sk-... legacy keys for new projects or accounts — all keys are now project-based (sk-proj-...). Any feedback on how to get this working would be greatly appreciated. Thank you!
