Single Selects don't work with JSON fields

Running: - [email protected] (using bun:sqlite) - [email protected] It seems like tables with a text("name", { mode: "json" }) column can only be selected if more than one entry get's selected (e.g. DB.query.Table.findMany().sync() or DB.select().from(Table).all()) If i use .get() or .findFirst() it gives me a error containing this

291 |       } else if (is(field, SQL)) {
292 |         decoder = field.decoder;
293 |       } else {
294 |         decoder = field.sql.decoder;
295 |       }
296 |       result[selectionItem.tsKey] = value === null ? null : decoder.mapFromDriverValue(value);
                                                                  ^

It looks like this originated from the utils.js file line 28 or relations.js line 296 (basically everytime it hits mapFromDriverValue) This is because for example the code in utils.js

const rawValue = row[columnIndex];
          const value = node[pathChunk] = rawValue === null ? null : decoder.mapFromDriverValue(rawValue);

const rawValue = row[columnIndex];
          const value = node[pathChunk] = rawValue === null ? null : decoder.mapFromDriverValue(rawValue);

Results in rawValue being undefined because row is something like

{
    "count(*)": 8
}

{
    "count(*)": 8
}

Or any other object containing id and other key value columns and the code tries to index this object

I was able to temporary fix it by doing following: utils.js

          const rawValue = row[columnIndex] || Object.values(row)[columnIndex];
          const value = node[pathChunk] = rawValue === null ? null : decoder.mapFromDriverValue(rawValue);

          const rawValue = row[columnIndex] || Object.values(row)[columnIndex];
          const value = node[pathChunk] = rawValue === null ? null : decoder.mapFromDriverValue(rawValue);

relations.js

      const value = mapColumnValue(row[selectionItemIndex] || Object.values(row)[selectionItemIndex]);
      const field = selectionItem.field;
      let decoder;
      if (is(field, Column)) {
        decoder = field;
      } else if (is(field, SQL)) {
        decoder = field.decoder;
      } else {
        decoder = field.sql.decoder;
      }
      result[selectionItem.tsKey] = value === null ? null : decoder.mapFromDriverValue(value);

      const value = mapColumnValue(row[selectionItemIndex] || Object.values(row)[selectionItemIndex]);
      const field = selectionItem.field;
      let decoder;
      if (is(field, Column)) {
        decoder = field;
      } else if (is(field, SQL)) {
        decoder = field.decoder;
      } else {
        decoder = field.sql.decoder;
      }
      result[selectionItem.tsKey] = value === null ? null : decoder.mapFromDriverValue(value);

I basically saw that the code tried to index the values so i just converted the single objects to its values so it could get indexed properly
