fail to read string list on certain line

[printfCalvin]

Kuzu failed to read the string list on line 5. TypeUtils::toString(col->readValue(j)) prints [,,,,,,,,,,,,,,,,,,,,,] in the test file. I suspect that this issue is related to copying strings in memory or in page. More specifically, the error could occur in InMemOverflowFile::copyString(const char* rawString, PageByteCursor& overflowCursor) in in_mem_file.pp.

    auto tableID = catalog->getReadOnlyVersion()->getNodeTableIDFromName("arrow_list");

    ifstream MyReadFile("dataset/copy-csv-arrow-node-test/list.csv");

    if (header) {

    }

    for (int j = 0; j < lines.size(); j++) {
        vector<string> split = CopyCSVArrowNodeTest::splitStrList(lines[j], ',');

        for (int i = 0; i < split.size(); i++) {

                name = "id";

            auto type = col->readValue(j).dataType;
            checkElement(type, split[i], col->readValue(j));
        }
    }
}

This is the message that I print out when the test fails:
