Example error:

error: (in promise) TypeError: error sending request for url (https://esm.sh/dd-trace@5.36.0&pin=v135&no-dts/package.json): error trying to connect: invalid peer certificate: UnknownIssuer 

const response = await fetch("https://esm.sh/dd-trace@5.36.0&pin=v135&no-dts/package.json");

 Solution, export this environment variable:

DENO_TLS_CA_STORE=system
