Fix KeyError

✅ Solution

KeyError in vLLM typically arises when the code attempts to access a dictionary key that does not exist, often due to missing configuration or an unexpected model structure. To fix this, verify that all required parameters and model components are correctly specified in the vLLM configuration or model loading process. If the error relates to missing IO processors for specific tasks, ensure the model architecture and its associated configuration accurately reflect the supported operations, or adjust the task to one with a defined processor.
