GetToken -- Harmony.Core.Utility.BridgeException: 'SYSTEM.ARGUMENTNULLEXCEPTION: No object for handle' #366
Comments

Additional information : I debug 'GetToken' and see the exception thrown from module VmsFunctions.dbl function 'Login' - Harmony.Core.Utility.BridgeException: 'SYSTEM.ARGUMENTNULLEXCEPTION: No object for handle' This exception was originally thrown at this call stack:

BridgeException means that the Traditional bridge routine running on VMS has thrown an exception. If you take a look at the RemoteStackTrace property of the thrown exception in .NET it will show you the remote stack trace for the code running on VMS. You can also take a look at the bridge log on VMS, that should also have the exception and the stack trace for that exception. |

When I debug the function ‘Login’ in VMS passing in the same parameters (username, password, environment), that function returns valid status. I checked the log file with errors requested from Postman, this is what I see. Looks like the error happens when the dispatcher function is serializing the data to return. messages from log file : Dispatcher: starting callblock processing with ContentLength 280 ContentType Serializer: {"jsonrpc":"2.0","id":2,"result":[{"Position":0,"Value":{"DataType":8,"PassedValue":1}},{"Position":4,"Value":{"DataType":1,"PassedValue":""}},{"Position":5,"Value":{"DataType":32,"PassedValue":["DEV_00253","DEV_00415","DEV_00423","DEV_00603","DEV_00900","DEV2_00841","DEV2_00853","DEV_00000"]}}]}

Hi Jeff,
Thank you for your quick response.
When I debug the function ‘Login’ in VMS passing in the same parameters (username, password, environment), that function returns valid status. I checked the log file with errors requested from Postman, this is what I see.
Looks like the error happens when the dispatcher function is serializing the data to return.

it seems a lot like for the environment "TEST_00423" your call to %login(arg1,arg2,arg3,arg4,arg5) is returning with a null value for arg4 or arg5 |
|
as i debugged %login(arg1,arg2,arg3,arg4,arg5) in VMS passing in "DEV_00423" and "TEST_00423", for both environments arg4 returns null and arg5 returns array of string. |
|
it looks like arg4 will throw this exception when you attempt to serialize it with the call to ArgumentData. The weird thing is that i don't appear to have that particular overload for ArgumentData so I'm not really sure what the implementation details are. The quickest fix will be to set arg4 to "" instead of ^null inside your login routine. |
When getting token from Postman, we get error for 'TEST' environment but not 'DEV'.
In VMS where the traditionalbridgehost.exe runs, we have one exe for both DEV and TEST environments. GetToken execute the 'Login' function passinging in username, password, and environment.
We can get token for DEV environment. But when we passing 'TEST' in to Login function, we got following error messages.
p.s. When i debug Login function in VMS with same parameter values, I can get valid login status.
