Malformed command sent to UAT if BuildCookRun command ends with a trailing slash ("\")

Including a trailing slash ("\") at the end of a BuildCookRun command sent to UAT results in UAT receiving a malformed command. If the command ends with a slash, the resulting command that UAT receives has a space added before the slash and "-compile" added immediately after the slash. The slash should instead be removed from the command before it is sent to UAT.

REGRESSION:
No. The same behavior occurs in 4.20.3. A different error prevented testing in Main.

1. Create a new Basic Code project.
2. Build the project for either the Test or Development configuration.
3. Open a Windows command line window.
4. Run the following command:

   Path\To\RunUAT.bat BuildCookRun -project="Path\to\Project.uproject" -noP4 -platform=Win64 -clientconfig=<Either Test or Development depending on what you used in step 2> -serverconfig=<Same as clientconfig> -skipcook -stage -pak -package -compressed -archive -archivedirectory=Path\to\destination\directory\
   

   • Make sure a trailing slash ("\") is included at the end of the command.
5. Run the command.

RESULT:
The process fails. The end of the command that is sent to UAT shows:

...-archivedirectory=Path\to\destination\directory \-compile

EXPECTED:
The process completes successfully.

WORKAROUND:
Make sure there is no trailing slash at the end of the command.
