Tabpy server awaits for the user to hit Enter on the tabpy server Console for the Tableau connection to establish/finish

Environment information:

• OS: Windows Server 2019
• Python version: 3.7.6
• TabPy release: Tabpy 2.9.0
  Describe the issue
  I've installed tabpy 2.9.0 on a python 3.7.6 python environment on a Windows Server 2019 server. Created a new conf file on a copy of default.conf with below updates:

TABPY_PWD_FILE = C:/Program Files/Microsoft/PyForMLS/Lib/site-packages/tabpy/tabpy_server/common/Password/users.txt

TABPY_LOG_DETAILS = true

Added a new user into the users.txt file.

Started the tabpy server from powershell console using below command:

tabpy --config "C:\Program Files\Microsoft\PyForMLS\Lib\site-packages\tabpy\tabpy_server\common\tabpy-server.conf"
PS C:\WINDOWS\system32> tabpy --config "C:\Program Files\Microsoft\PyForMLS\Lib\site-packages\tabpy\tabpy_server\common\tabpy-server.conf"

Using Tableau Desktop Pro2022.3 running on a Windows 10 workstation, I then connect to this Tabpy server by providing Server name, port, username and password. The connection is hanging, until I hit Enter on the above console at which point on Tableau desktop side, it shows a successful connection been established, and on the PS console it shows below details confirming this connection.

The tabpy server is running under my userid.

Is there a way to automate this connection acceptance please, without a user having to hit Enter?

The issue had been with the conf file having forward slashes in TABPY_PWD_FILE setting. Once they were converted to backslashes, the issue was gone. Connections establish straightway without having to hit Enter anymore.

TABPY_PWD_FILE = C:\Program Files\Microsoft\PyForMLS\Lib\site-packages\tabpy\tabpy_server\common\Password\users.txt
