After updating the library, the application on NestJs stopped starting

[AntonBozhenko]

Previously, in some of our projects, both in the dev environment and locally, we did not connect to real data but used random strings (in RMQ_USERNAME, RMQ_PASSWORD, RMQ_HOST). The application would start and display errors in the console. However, after the latest update (5.6.1), the application fails to start entirely. The configuration settings are provided below.

export const RmqConfig: RabbitMQConfig = {
  uri: `amqp://${process.env.RMQ_USERNAME}:${process.env.RMQ_PASSWORD}@${process.env.RMQ_HOST}`,
  connectionInitOptions: { wait: false },
  exchanges,
  queues,
  channels: {
    'main-channel': {
      prefetchCount: 1,
      default: true,
    },
  },
  enableControllerDiscovery: true,
};

@Module({
  imports: [RabbitMQModule.forRoot(RabbitMQModule, RmqConfig)],
  exports: [RabbitMQModule],
})
export class RmqModule {}

@AntonBozhenko Are you able to include the error messages that you see, the reproduction above looks correct but I don't know what errors were talking about here

@underfisk
The screen shows the start of the application on library version 5.3.0

With library version 5.6.1 the error is the same, but the application does not start.
The error occurs because my local RabbitMq server is not running.
It looks like connectionInitOptions: { wait: false } is not working.

@AntonBozhenko Are you able to identify if in the previous version 5.6.0 this still happens? I'd like to understand when this started happening

[AntonBozhenko]

@underfisk on version 5.4.0 everything is fine, but on all newer versions the application does not start

I belive that there is an issue in

nestjs/packages/rabbitmq/src/amqp/utils.ts

Line 32 in 6ca2d16

/^amqps?:\/\/(([^:]+):([^@]+)@)?([^:/]+)(:[0-9]+)?(\/.*)?$/;

The / is not escaped, I belive it should be changed to

/^amqps?:\/\/(([^:]+):([^@]+)@)?([^:\/]+)(:[0-9]+)?(\/.*)?$/;
