angular 5 Expected 0 arguments, but got 1

Question

I have a jhipster project. It is running fine in dev mode. When I try to build in production mode (using the cmd "mvnw -Pprod"), I am getting the error :

ERROR in src\main\webapp\app\entities\ext-task\ext-task-group-list\ext-task-group-list.component.html(1,457): : Expected 0 arguments, but got 1. src\main\webapp\app\entities\ext-task\ext-task-group-list\ext-task-group-list.component.html(1,665): : Expected 0 arguments, but got 1. src\main\webapp\app\entities\ext-task\ext-task-list-template\ext-task-list-template.component.html(1,302): : Expected 0 arguments, but got 1. src\main\webapp\app\entities\ext-task\ext-task-list-template\ext-task-list-template.component.html(1,505): : Expected 0 arguments, but got 1.

All the 4 errors point to line 1, which is empty.

In order to find the actual line number, I tried following cmd (found in so).

yarn run cleanup && yarn run webpack:prod:main && yarn run clean-www

Got the same error.

How do I find the error line number? Is there any debug option available in mvnw to display more info? How to resolve this error?

Okay, if you are using tree shaking, ex. with --aot, especially at build time, it'll check the functions in your templates.

This error states that in your template template.component.html, it calls a function with no arguments, but instead you put one after that, ex. open(true)

You should be able to find the source code. It should sit inside src\main\webapp\app\entities\ext-task\ext-task-group-list\ext-task-group-list.component.html, search for any function called inside this template.
