DynamoDB Query Filter Expression Doesn't Work

[hxk1633]

Describe the bug

The filter_expression method for a dynamodb query does nothing. I try the same filter expression in the AWS DynamoDB console and it works as expected. I'm not sure how to debug this issue on my end.

Regression Issue

• Select this option if this issue appears to be a regression.

Expected Behavior

I expect my query filter expression to return results.

Current Behavior

The query filter expression returns an empty result with no errors.

Reproduction Steps

This is the full code of the query to reproduce the issue.

      let gsi2_pk = format!("STATUSES ACCOUNT#{}", &account_id.to_string());
      let mut req = self
          .client
          .query()
          .table_name(&self.table_name)
          .index_name("StatusHistoryByAccount")
          .scan_index_forward(false)
          .key_condition_expression("GSI2PK = :account_id")
          .expression_attribute_values(":account_id", AttributeValue::S(gsi2_pk))
          .limit(limit);

      if let Some(next) = next {
          req = req.set_exclusive_start_key(Some(next.into()));
      }

      if let Some(sort) = sort {
          match sort.sort_by.as_str() {
              "createdAt" => {
                  req = match sort.sort_order.as_str() {
                      "asc" => req.scan_index_forward(true),
                      "desc" => req.scan_index_forward(false),
                      _ => req,
                  }
              }
              _ => (),
          }
      }

      if let Some(day) = &filters.day {
          req = req.filter_expression("DayKey = :day");
          req = req.expression_attribute_values(":day", AttributeValue::S(day.to_owned()));
      }   
  
      let res = req.send().await?;

      let statuses = match res.items {
          Some(items) => items
              .into_iter()
              .map(|item| item.try_into())
              .collect::<Result<Vec<DeviceStatus>, _>>()?,
          None => Vec::default(),
      };
      let next = res.last_evaluated_key.map(|m| m.into());
      Ok(DeviceStatusRange { statuses, next })
  }
