Fix LettaInvalidArgumentError

✅ Solution

LettaInvalidArgumentError in memgpt usually stems from incorrect or missing arguments when initializing or using embedding models within archival or memory configurations. Ensure that the correct embedding model name, dimensions, and API keys (if required) are explicitly passed during agent and archival memory initialization; double-check your `config.json` and command-line arguments for accuracy. Specifically, verify that `agent_config.embeddings_config.embedding_model` matches a valid model and is consistently used across the application.
