revealItem compilation error when "strict": true in tsconfig.json

[sreddim]

Hi ,
I have used revealItem and $isSelected to programatically select a row in Table.
This works when I define the api as type object and my tsconfig.json does not have strict: true rule.
For several other reasons and issues caused during router parameter values typecasting I am using strict: true rule now.

Since then I am getting api.revealItem compilation error and view does not open.

arendetableApi: any;
I have tried to initialize this in the constructor as below
this.arendetableApi= {};

Still having this error. Please help.
My programming environment: Aurelia , Typescript, webpack with VSCode

Inner Error:
Message: this.arendetableApi.revealItem is not a function
Inner Error Stack:
