FetchError: request to https://localhost:8000/___graphql failed, reason: unable to verify the first certificate

Hello,

The first time I run Gatsby with SSL activated, an error occured. So now the error is fixed, when I
run gatsby develop "-S", I got this :
FetchError: request to https://localhost:8000/___graphql failed, reason: unable to verify the first certificate
My tought is I haven't setting up my SSL certificate and I don't know how to "reset" it to setting up in a good way.
I tried to clean gatsby's cache and rm -rf node_modules, change nothing.

This is a known bug related to #15441 you can use "NODE_TLS_REJECT_UNAUTHORIZED=0 gatsby develop --https" as a workaround though until it gets fixed though, so i'm going to close this for now

Thx for the answer.
FYI the related bug your are quoting is actually this bug. ^^
Just by curiousity, what's the bug ?

Seems like this is it #14990

anyone coming here: if you are running SSL certificates for local development, using mkcert: you might need to run

export NODE_EXTRA_CA_CERTS="$(mkcert -CAROOT)/rootCA.pem"
