Error when running "populate the vector index"

Hi, I am trying to use the notebook alongside the video. I run into the following error when running the first code block in the part populate the vector index.

ClientError: {code: Neo.ClientError.Procedure.ProcedureCallFailed} {message: Failed to invoke function `genai.vector.encode`: Caused by: com.neo4j.genai.vector.MalformedGenAIResponseException: Unexpected HTTP response code: 500 Internal Server Error - 500 error

Is something wrong? Or just a temporary problem?

Weird, after re-running from the beginning, now it works. Leave it here for others with the same problem.
