Dynatrace App install error SELF_SIGNED_CERT_IN_CHAIN

[Sachinpai]

I was trying to follow the Sample App creation document Five minutes to your first app | Dynatrace Developer. 

Getting error while running npx dt-app@latest create --environment-url <URL>

Searching for template repositories...Error reading repository archive: TypeError: fetch failed

Hi @Sachinpai 

Maybe there is somewhere a firewall in place which does SSL termination and therefore you are getting this error.
To disable ssl check you can do following

on Windows (powershell), run following command

$Env:NODE_TLS_REJECT_UNAUTHORIZED='0'; & npx dt-app@latest create

On Linux/unix, run following command: 

NODE_TLS_REJECT_UNAUTHORIZED='0' npx dt-app@latest create

Please let me know if this has solved your issue

Best,
Sini
