Issue with Object type inclusion | Ballerina | Page 1

Hi team,
Currently, I'm trying to implement a class by including the Object type (interface) that is defined in another package. In other word, my interface is in separate package and my class implementation in a different package.

For example,
In package - A ( ballerinax/health.fhir.r4)

public type Finder readonly & object {
    public isolated function addCodeSystems(CodeSystem[] codeSystems) returns error;
}

Here, the CodeSystem is record defined in the same packge (package - A)

In package - B

public readonly class FinderImpl {
    *r4:Finder;
    
    public isolated function addCodeSystems(r4:CodeSystem[] codeSystems)           returns error {
      // The further implementation
    }
}

While doing this I getting the below error.

mismatched function signatures: expected 'public function addCodeSystems(ballerinax/health.fhir.r4:3.0.5:CodeSystem[] ) returns error', found 'public function addCodeSystems(ballerinax/health.fhir.r4:3.0.5:CodeSystem[] codeSystems) returns error'

Even though the method signatures are identical to each other, it returning this compile time error.

Note - These errors are occurring only if the method definitions have parameters.
For instance, in this (below) case there are no such issues.

type Person object {
    string name;

    function getName() returns string;
}; 

class Engineer {
    *Person;

    function getName() returns string {
        return self.name;
    }
}
