Jem Mrnewliu Do you really need a friendbot? Or are you just looking for a way to create accounts? Because you can do the latter without the former.
Vishwas1 Is the NODE_SEED value we set in the config file of stellar-core is what root account secret is ?
dzham Maybe try with an older version of stellar core? Removing "signers" is a quite recent change, so your tutorial might not be compatible with it.
