   I've had the same problem when deleting and re-creating a function in standalone mode:
   
   ```
   (base) ➜  apache-pulsar-2.11.0 bin/pulsar-admin functions create --function-config-file basic-function.yaml --jar basic-function-0.0.1-SNAPSHOT.nar
   Created successfully
   (base) ➜  apache-pulsar-2.11.0 bin/pulsar-admin functions delete --tenant test --namespace test-namespace --name string-to-string
   Deleted successfully
   (base) ➜  apache-pulsar-2.11.0 bin/pulsar-admin functions create --function-config-file basic-function.yaml --jar basic-function-0.0.1-SNAPSHOT.nar
   Package 'function://test/test-namespace/string-to-string@0' metadata already exists
   
   Reason: Package 'function://test/test-namespace/string-to-string@0' metadata already exists
   ```
   
   For some reason the `{PULSAR_HOME}/packages-storage/function/<tenant>/<namespace>/<function-name>` doesn't get removed causing this error.
   
   If you manually delete the folder, you can recreate (maybe also update) the function.
