Inconsistent result from function for a struct with an array of enums

[petertonysmith94]

Summary

Experiencing an issue with the encoded response of the following contract function. We have replicated this issue in both the TS-SDK and RS-SDK.

From the function, we return the following struct:

// 0x000000000000000100000000000000010000000000000001
StructWithEnumArray {
    a: [EnumWithNative::Pending, EnumWithNative::Pending, EnumWithNative::Pending],
}

However, the result from the function call is the following:

// 0x000000000000000100000000000000000000000000000001
StructWithEnumArray {
    a: [EnumWithNative::Pending, EnumWithNative::Checked, EnumWithNative::Pending],
}

The return data receipt for the function call is the follow:

// raw receipt
{
  id: '0xa52541ced4559cf68e923e81ffc900d6855994bfabad4dd9f24c4dfea8e4f183',
  pc: '44544',
  is: '11712',
  ptr: '67107840',
  digest: '0x639809bc6d63798b4571d10a078c77219a7191b65eb30d8b08415d8631c1dbd9',
  len: '24',
  receiptType: 'RETURN_DATA',
  data: '0x000000000000000100000000000000000000000000000001',
}

Expected

The contract method should return:

StructWithEnumArray { a: [Pending, Pending, Pending] }

Actual

The contract method actually returns:

StructWithEnumArray { a: [Pending, Checked, Pending] }

Additional notes

When we remove the input arguments for this function, we receive the correct expected result.

fn return_struct_with_enum_array() -> StructWithEnumArray {
    const EXPECTED_ENUM = EnumWithNative::Pending;
    const EXPECTED: StructWithEnumArray = StructWithEnumArray {
        a: [EXPECTED_ENUM, EXPECTED_ENUM, EXPECTED_ENUM],
    };

    EXPECTED
}
