[Bug]: Incorrect compiler incompatible types error when a type is of the expected type

[chamajay]

Description

The code snippet in the "Steps to Reproduce" section triggers an incompatible types error, even though the variable has the expected type. As temporary workarounds, a type cast or var can be used.

Steps to Reproduce

import ballerinax/health.fhir.r4;

r4:ResourceAPIConfig apiConfig = {
    resourceType: "",
    profiles: [],
    defaultProfile: (),
    searchParameters: [],
    operations: [],
    serverConfig: (),
    authzConfig: ()
};

public function main() {
    r4:OperationConfig[] & readonly operations = apiConfig.operations;
}

This triggers the compiler error: ERROR [main.bal:(14:50,14:70)] incompatible types: expected '(ballerinax/health.fhir.r4:4.3.3:OperationConfig[] & readonly)', found '(ballerinax/health.fhir.r4:4.3.3:OperationConfig[] & readonly)'

Affected Version(s)
