setLogLevels is not a function

[mgill2190]

Hey,

nestjs - 8.4.7
nest-winston - 1.6.2
winston - 3.8.0

On running npm run start:dev. I get the following error:

(node:75942) UnhandledPromiseRejectionWarning: TypeError: _a.setLogLevels is not a function
    at Function.overrideLogger (/node_modules/@nestjs/common/services/logger.service.js:121:90)
    at NestFactoryStatic.registerLoggerConfiguration (/node_modules/@nestjs/core/nest-factory.js:141:37)
    at NestFactoryStatic.createApplicationContext (/node_modules/@nestjs/core/nest-factory.js:72:14)

    at bootstrap (/src/main.ts:28:24)
    at processTicksAndRejections (internal/process/task_queues.js:95:5)

main.ts -> bootstrap function has:

  const app = await NestFactory.create(AppModule);
  app.useLogger(WinstonModule.createLogger({
    format: winston.format.uncolorize(),
    transports: [
      new winston.transports.Console({
        format: winston.format.combine(
            winston.format.timestamp({
              format: 'YYYY-MM-DD HH:mm:ss',
            }),
            winston.format.ms(),
            nestWinstonModuleUtilities.format.nestLike()
        ),
      })
    ]
  }));

Error seems to be thrown from nest's logger service calling _a.setLogLevels(logger):

static overrideLogger(logger) {
      var _a;
      if (Array.isArray(logger)) {
          Logger_1.logLevels = logger;
          return (_a = this.staticInstanceRef) === null || _a === void 0 ? void 0 : _a.setLogLevels(logger);
      }
      if ((0, shared_utils_1.isObject)(logger)) {
          if (logger instanceof Logger_1 && logger.constructor !== Logger_1) {
              const errorMessage = `Using the "extends Logger" instruction is not allowed in Nest v8. Please, use "extends ConsoleLogger" instead.`;
              this.staticInstanceRef.error(errorMessage);
              throw new Error(errorMessage);
          }
          this.staticInstanceRef = logger;
      }
      else {
          this.staticInstanceRef = undefined;
      }
  }

Would really appreciate anyone showing some light on how I could get passed this issue? Thanks.

A solution would be great when closing it 😄, @mgill2190

@nealoke I didn't actually have a solution. A colleague managed to get Winston set up on nest without experiencing this issue. I pulled down his branch and worked fine so I assumed the issue was local to me and closed the issue to save someone else wasting time trying to fix.

Are you experiencing the same issue? Feel free to copy & paste above into new issue if you need help.
