Type annotation in catch clause is not supported

Rule arkts-no-types-in-catch

Severity: error

In TypeScript, catch clause variable type annotation must be any or unknown if specified. As ArkTS does not support these types, omit type annotations.

TypeScript

    try {
        // some code
    }
    catch (a: unknown) {
        // handle error
    }

ArkTS

    try {
        // some code
    }
    catch (a) {
        // handle error
    }
