`“attrValue:”XXX”` is not always correct. In fact, there could be different possibilities:

* `“attrVlaue:”XXX”` (for simple strings)
* `“attrValue: { ... }"` (for JSON objects)
* `“attrValue: [ ... ]"` (for JSON vectors)

In addition, there is a typo in the field name: `"attrVlaue:` -> `"attrValue"` (don't miss the second quote).
