Hi Ali,
Thanks for your message,
Firstly, we need to make sure that you are using the up-to-date Symphony Generator along with the correct command.
Can you use the Symphony Generator from the FINOS GitHub respository: https://github.com/finos/generator-symphony
If you are using NPM - you can simply use this command to install it:npm install -g @finos/generator-symphony
The following command will allow you to run the Symphony Generator & generate the BDK bot scaffold:yo @finos/symphony
Please let us know if you continue have any issues.
