As in this case (without using `Annotated`) we have to replace the default value `None` in the function with `Query()`, we now need to set the default value with the parameter `Query(default=None)`, it serves the same purpose of defining that default value (at least for FastAPI).

So:

            dynamicTable = doubled
          }
          index = nextHeaderIndex--
          dynamicTable[index] = entry
          headerCount++
        } else { // Replace value at same position.
          index += dynamicTableIndex(index) + entriesEvicted
          dynamicTable[index] = entry
        }
        dynamicTableByteCount += delta
      }

			panic(fmt.Sprintf("header: %x != object id: %x", x.versions[idx].header.VersionID, dst.getVersionID()))
		}
	}
	return &dst, err
}

// setIdx will replace a version at a given index.
// Note that versions may become re-sorted if modtime changes.
func (x *xlMetaV2) setIdx(idx int, ver xlMetaV2Version) (err error) {
	if idx < 0 || idx >= len(x.versions) {

        return parseItem(false, isDigit, buf);
    }

    private static Item parseItem(boolean isCombination, boolean isDigit, String buf) {
        if (isCombination) {
            return new CombinationItem(buf.replace("-", ""));
        } else if (isDigit) {
            buf = stripLeadingZeroes(buf);
            if (buf.length() <= MAX_INTITEM_LENGTH) {
                // lower than 2^31
                return new IntItem(buf);
