hey guys, when i try to query a DynamoDB table with filters, i get an error:
```Invalid KeyConditionExpression: Attribute name is a reserved keyword; reserved keyword: key```

table construct spec:
```const table = new sst.Table(this, `MyTable`, {
  fields: { pk: sst.TableFieldType.STRING, sk: sst.TableFieldType.STRING },
  primaryIndex: { partitionKey: "pk", sortKey: "sk" },
});```

<@U035D7Q26CF> what is your filter expression you're querying?

in one of the screenshots, `pk` `equal to` `123`

although it doesn’t seem to work for any value :confused:

seems to only happen to the condition`equal to`

seems like a backend related issue, could you try changing the filter of `sk` to something else and try?

could it be because my keys actually have `#` in them? e.g. `foo#bar`

I meant, change the filter on `sk` to something else other than `equal to`

remove the `sk` value and change the dropdown filter any try

for reference, my sample data
```[
{
  "createdAt": 10,
  "sk": "bar",
  "pk": "foo#baz",
  "updatedAt": 20
},
{
  "createdAt": 10,
  "sk": "baz",
  "pk": "foo#bar",
  "updatedAt": 20
}
]```

i believe `KeyConditionExpression` should actually be
```#pk = :pk AND #sk = :sk```


in this particular case as well, `#key` instead of `key`

<@U01MV4U2EV9> can u take a look at this when u get a chance?

fyi, quick PR here
