LoopBack version 4 Interceptor issue

Question

I am trying to call a log function which is in the document using interceptor in LoopBack 4 as illustrated below;

@intercept(log) // `log` is an interceptor function
export class PingController {

}

log function in LoopBack 4 docs

const log: Interceptor = async (invocationCtx, next) => {
    console.log('log: before-' + invocationCtx.methodName);
    // Wait until the interceptor/method chain returns
    const result = await next();
    console.log('log: after-' + invocationCtx.methodName);
    return result;
};

But I get an error;

cannot find name Interceptor

What am I doing wrong and how can I resolve it?

Answer 1

import { Interceptor } from '@loopback/context';

Able to get Interceptor Object from @loopback/context latest version
