Historical Data Is Not Returned When the Querying Historical Device Data API Is Called

The pageNo parameter in the Querying Historical Device Data API indicates the page number to be queried.
  • If the value is 0, the first page is queried.
  • If the value is null, pagination query is not performed.
  • If the value is an integer greater than or equal to 0, pagination query is performed.

When this issue occurs, set pageNo to 0 to query the content on the first page.
