04/20/2023, 6:17 AMHi, I'm trying to build supertoken-core from source, so I'm following this [md](https://github.com/supertokens/supertokens-core/blob/master/CONTRIBUTING.md).
I've the supertokens-root and I'm trying to run the scripts first before starting to modify the source.
I'm getting the following error when i try to run
./startTestEnvr

04/20/2023, 8:02 AMThanks @rp_st. It is running now, how come I use my local db for supertoken core? config.yaml doesn't have flags for it.

04/20/2023, 8:03 AMyou need to see the devConfig.yaml in the supertokens-postgresql folder (if you have loaded postgrsql). By default, it works with an in memory db.
For setting up with psql, see this: https://github.com/supertokens/supertokens-postgresql-plugin/blob/master/CONTRIBUTING.md

04/20/2023, 8:58 AMHi @rp_st , One quick doubt, we have a table named jwt_signing_keys table in the supertokens db right, it has key_string which has the keys seperated by '|'. I could see one is public key and what's the other and is it okay to store the public key on the server?

04/20/2023, 9:04 AM1. the other one is the private key
2. the public key is, well, public. it is ok to store on the server, plus the JWKs endpoint returns them anyway.
