Describe the bug

  • GetStateAsync fails while the HTTP Api does not when a projection state is returned.
  • Http Api GET projection/{name}/state might return an empty result, the GetStateAsync operation fails in such cases
    The excetpion is System.Text.Json.JsonReaderException

To Reproduce
Steps to reproduce the behavior:
the code in this gist reproduces the error when there is a state returned by the HTTP Api : https://gist.github.com/ylorph/a27997621b3e6e26e635223c30714912

Expected behavior
GetStateAsync should return the data when it is available
GetStateAsync should not fail when there is no data to return

Actual behavior
GetStateAsync fails with an expection in all cases
