compiler
Is this a regression?
Yes
Description
Getting the below error, even though the self-signed certificate is trusted. Happening in SSR.
Error object: HttpErrorResponse { headers: _HttpHeaders { headers: Map(0) {}, normalizedNames: Map(0) {}, lazyInit: undefined, lazyUpdate: null }, status: 0, statusText: 'Unknown Error', url: 'https://localhost:7257/articles', ok: false, type: undefined, redirected: undefined, responseType: undefined, name: 'HttpErrorResponse', message: 'Http failure response for https://localhost:7257/articles 0 undefined', error: TypeError: fetch failed at node:internal/deps/undici/undici:15845:13 at process.processTicksAndRejections (node:internal/process/task_queues:103:5) { [cause]: Error: self-signed certificate; if the root CA is installed locally, try running Node.js with --use-system-ca at TLSSocket.onConnectSecure (node:_tls_wrap:1631:34) at TLSSocket.emit (node:events:508:28) at TLSSocket._finishInit (node:_tls_wrap:1077:8) at ssl.onhandshakedone (node:_tls_wrap:863:12) { code: 'DEPTH_ZERO_SELF_SIGNED_CERT' } } } Only workaround I found so far is to set process.env['NODE_TLS_REJECT_UNAUTHORIZED'] = '0'
Setting NODE_EXTRA_CA_CERTS didn't help.
