You are missing the configuration file of this CorDapp as explained here ; you must:
config
folder inside your node's cordapps
folder (ie node-folder/cordapps/config
).membership-service.conf
file. // Whitelist of accepted BNOs. Attempt to communicate to not whitelisted // BNO would result into an exception bnoWhitelist = ["O=BNO,L=New York,C=US", "O=BNO,L=London,C=GB"] // Name of the notary to use for BNO transactions such as membership approval notaryName = "O=Notary,L=Longon,C=GB"
The CorDapp that you're using relies on a configuration file (the above 3 steps create that file) and it causes the NullPointerException
when it's missing. To understand more about CorDapp configuration files, read my article .
On a side note, according to this ; the CorDapp that you're using will be deprecated on 31 September 2020.
