Porting is completed. However, the following test (error1.bal) fails with a CCE. Investigating into it.

// EL<:E
// ER1<:E
// ER1<:ER2
// ER2<:E
// ER2<:ER1
type EL error<record {| int[] codes; |}>;
type ER1 error<record {| ER1? e; |}>;
type ER2 error<record {| ER2|() e; |}>;
type E error;

The above CCE was due to a porting mistake. It is resolved now. Encountered another issue when enabling data/error1.bal test case. It is not related to the error port. Created a separate issue #42662.

Closing with #42663
