Hi @shyed_abuthahir,

I've logged incident INC13465669 for our engineering team to investigate the issue, I'll provide you with an update once I hear back from engineering.

Hi @shyed_abuthahir,

The code for the VDP Playground may need to be updated. However, please check to ensure that the key you are using in the tools starts with "-----BEGIN RSA PRIVATE KEY-----"

If it doesn't, see if you can run the following command by using the resulting key instead.

openssl rsa -in privateKey.pem -out key.pem

If this still doesn't work, you might have to use the code snippet instead of the VDP Playground Tool.

After you do this, please let me know if the issue is fixed.
