Describe the bug / error
I have been getting this error after trying to execute gulp trust-dev-cert on a new web part project and haven't been able to fix it, please kindly help. I followed the set up process here https://learn.microsoft.com/en-us/sharepoint/dev/spfx/set-up-your-development-environment and also tried in my other PC but still throws the same error. I am executing this statement from the webpart solution folder. It does give me the Certificate installation prompt for localhost and after the error is thrown, it creates rushstack-serve.key, rushstack-serve.pem files in .rushstack folder. Here is the error:
Thank you.
Steps to reproduce
- Install node v16.13.0
- install gulp cli, yoeman and sharepoint generator
- Create webpart with the generator scaffolding
- Run gulp trust-dev-cert
Expected behavior
certificate successfully installed and running gulp serve would bring up the workspace
