1. Manage Typescript and Angular extension in servman.
2. Create a user defined UA for Typescript
3. Run the analysis on Typescript source code.

All the Typescript objects would be missing from Dashboard as nothing has been analyzed.

The issue occurs because of the fact that you are running the analysis by using a network path as your deploy folder. For ex: \\<server_name>

So to fix the issue select either of the below:

1. Map the network location to a Drive/Volume letter.
   OR
2. Use the attached file __init__.py and replace it in your installation folder with the existing one below :
   <CAST_Installation_folder>\ThirdParty\Python34\Lib\site-packages\cast\application
   OR
3. Take the latest version of lib_cast_upgrade_x_y_z.zip from Typescript Extension and patch it to your extension folder and run the analysis.
