TypeError: metatype is not a constructor

Hi Team,

My code was running properly and all of a sudden I'm getting this error.

[Nest] 10348 - 16/02/2020, 11:14:40 pm [ExceptionHandler] metatype is not a constructor +17ms TypeError: metatype is not a constructor at Injector.instantiateClass (C:\Users\susha\Documents\Nest.js\Task Management\node_modules\@nestjs\core\injector\injector.js:288:19) at callback (C:\Users\susha\Documents\Nest.js\Task Management\node_modules\@nestjs\core\injector\injector.js:75:41) at processTicksAndRejections (internal/process/task_queues.js:97:5) at async Injector.resolveConstructorParams (C:\Users\susha\Documents\Nest.js\Task Management\node_modules\@nestjs\core\injector\injector.js:116:24) at async Injector.loadInstance (C:\Users\susha\Documents\Nest.js\Task Management\node_modules\@nestjs\core\injector\injector.js:79:9) at async Injector.loadInjectable (C:\Users\susha\Documents\Nest.js\Task Management\node_modules\@nestjs\core\injector\injector.js:32:9) at async Promise.all (index 0) at async InstanceLoader.createInstancesOfInjectables (C:\Users\susha\Documents\Nest.js\Task Management\node_modules\@nestjs\core\injector\instance-loader.js:57:9) at async C:\Users\susha\Documents\Nest.js\Task Management\node_modules\@nestjs\core\injector\instance-loader.js:28:13 at async Promise.all (index 6)

I've tried installing and uninstalling the node_modules it still didn't help.

I can't find the problem too using the error stack.

Could anyone please check where is it breaking?

This is the link to my repository in which I'm facing the issue.

Thanks!

Hi Team, this worked after I re-built the project. I don't understand what's the problem!
