Details
I am using my work PC and suspect that our firewalls or other security software may be blocking the self-signed certificate.

🤖 AI-Generated Preliminary Analysis:

From the provided error message, it appears that the problem is related to a self-signed certificate in the certificate chain when making an API call to the Developer Portal. This usually indicates that the issue might be related to your network configuration, specifically, the presence of a firewall or other security software that is interfering with the connection.

Steps to Resolve

1. Check Network Configuration:

   • Since you mentioned using a work PC, it is likely that your network is behind a corporate firewall or proxy that is intercepting SSL/TLS traffic and replacing certificates with its own self-signed certificate. You need to configure your environment to trust this certificate.

2. Add Self-Signed Certificate to Trusted Root:

   • Locate the self-signed certificate used by your company's proxy/firewall.
   • Add this certificate to the trusted root certificate authorities on your machine. Here's how you can do it:
     1. Open the Run dialog (Win + R), type certlm.msc, and press Enter to open the Certificate Manager.
     2. Navigate to Trusted Root Certification Authorities -> Certificates.
     3. Right-click and choose All Tasks -> Import.
     4. Follow the wizard to import the certificate.

3. Set up Proxy Configuration:

   • If you are behind a proxy, ensure that Visual Studio and your environment are configured to use the proxy.
   • You can set the proxy settings in Visual Studio by navigating to Tools -> Options -> Environment -> Web Browser -> Proxy Settings.

4. Bypass SSL Verification (Temporary Solution):

   • As a temporary workaround (not recommended for production), you can bypass SSL verification. This can be done by setting an environment variable:

     set NODE_TLS_REJECT_UNAUTHORIZED=0

   • Note: This is not a secure practice and should only be used for debugging purposes.

5. Retry the Operation:

   • After making the above changes, retry the Prepare Teams App Dependencies step in Visual Studio.

@iwaldman in the meantime, try going to dev.teams.microsoft.com (Teams Developer Portal) and creating an app there as a test. Please let me know if that is successful.
