MLFlow throws and error when serving a model: The configured tracking uri scheme: 'file' is invalid for use with the proxy mlflow-artifact scheme

I'm trying to serve a model locally as a REST endpoint using MLFlow CLI. MLflow version is 2.11.3. Following are the arguments that I'm using.

mlflow models serve -m "runs:/7782c4a700cc49c1a04f9ce608d90358/knnmodel" --env-manager local --port 5000

Following is the exception:

    raise MlflowException(

It seems like MLflow the artefact cannot be accessed from the MLflow Webserver. Any fixed for this?

you need to export this variable

export MLFLOW_TRACKING_URI=http://127.0.0.1:<PORT of the mlflow server>
