Playground custom LLM server - api key validation

[matined]

Hi, I wanted to use the Langfuse Playground with my custom agent hosted on the server, but I get the api key validation error:

Do you know how to resolve it? I cannot find any info on how the api key is validated.

Thanks in advance 🙏

The error message "Cannot read properties of undefined (reading 'message')" is likely triggered in the ChatMessageComponent if the message prop is not properly passed or is undefined. This can occur if the API key object or related data is not correctly initialized or passed to the component ^[1].

To resolve the API key validation issue, ensure that the API key object is correctly defined with all required properties. The expected properties for the API key object in Langfuse include:

• projectId: A non-empty string.
• secretKey: A non-empty string.
• provider: A non-empty string.
• adapter: A valid enum value of LLMAdapter.
• baseURL: An optional valid URL string.
• withDefaultModels: An optional boolean.
• customModels: An optional array of non-empty strings.
• config: An optional BedrockConfigSchema object ^[2].

Additionally, make sure that the API key is correctly retrieved and validated in the Langfuse Playground. The API key is retrieved from the database and validated using the LLMApiKeySchema.safeParse method. If the parsing is unsuccessful, it can lead to errors ^[3].

Check that all fields are correctly filled and that the API key is properly configured according to these requirements. This should help resolve the validation error.

I resolved the issue.

Langfuse sends a request to /chat/completions with stream = false, so I just had to implement the non-streaming option.
