daml test command is failed with: damlc: user error (Failed to start scenario service: BErrorClient

Question

I just created my first DAML project and wrote a basic template. When I try to test it, getting following error: damlc: user error (Failed to start scenario service: BErrorClient (ClientIOError (GRPCIOBadStatusCode StatusUnknown (StatusDetails {unStatusDetails = "Stream removed"}))))

Below is my daml code (template)

    module Rent where
    
    template RentalAgreement
      with
        landlord : Party
        tenant : Party
        terms : Text 
      where
        signatory landlord

rentTest = scenario do
  
  p1 <- getParty "party 1"
  p2 <- getParty "party 2"
  
  submit p1 do 
    create RentalAgreement 
      with 
        landlord = p1; tenant = p2; terms = "sample"
  
  
  assert True

daml build command is successful.

Compiling first-daml to a DAR.
Created .daml\dist\first-daml-0.0.1.dar

daml test command is failed.

Answer 1

daml test opens a separate gRPC server and connects to that. Based on the error, it looks like this connection isn’t working properly. Do you have some kind of firewall enabled that could block this?

Do you encounter the same issue in daml studio?

I tried reproducing this in SDK 1.6.0 but was unable to do so. It would be great if you could provide the SDK version and the operating system you are running this on.

gRPC will use the http_proxy and https_proxy environment variables. Try setting no_proxy=127.0.0.1 to disable it for the requests to localhost.
