Class 'Subject' incorrectly extends base class 'Observable'. Types of property 'lift' are incompatible. Type '(operator: Operator) => Observable' is not assignable to type '(operator: Operator) => Observable'. Type 'Observable' is not assignable to type 'Observable'. Type 'T' is not assignable to type 'R'.
Its a typescript issue :
Navigate to your ionic project folder and then please try running this command in your terminal :
npm install [email protected]
