Hi, I am trying the example given in node-casbin readme and facing following error.

error: uncaughtException: Unexpected token import

@HarshadMohape0904 The await method is not working. Please use the following function.

casbin.newEnforcer("../path/model.conf", "../path/policy.csv").then(function (enforcer) {
          console.log("success =  ", enforcer)
}).catch(function (error) {
            console.log("error =  ", error)
})

Thanks, @akshay27395 I tried it and it worked…!

I tried the above solution but it leads me to a new error as below.

var test = await casbin.newEnforcer("../path/model.conf", "../path/policy.csv").then(function (enforcer) {
                         ^^^^^^
