Failed to decrypt Vantage API key. Check your salt key confi

Error message

Failed to decrypt Vantage API key. Check your salt key configuration.

What it means

Raised when the stored Vantage api_key in the LiteLLM_Config table cannot be decrypted by decrypt_value_helper, which returns None on failure. Means the value was encrypted with a different or missing LITELLM_SALT_KEY than the one currently configured, so the stored ciphertext is unrecoverable until the salt key is corrected or the setting is re-initialized.

Solutions

1. Ensure LITELLM_SALT_KEY is unchanged from when the Vantage API key was stored; re-save the key if the salt key rotated.
