471292050,MDU6SXNzdWU0NzEyOTIwNTA=,563,incorrect json url for row-level data?,10352819,closed,0,,,0,2019-07-22T19:59:38Z,2019-10-21T02:03:09Z,2019-10-21T02:03:09Z,CONTRIBUTOR,,"While visiting [this example page](https://register-of-members-interests.datasettes.com/regmem-98dc8b7/people/uk.org.publicwhip%2Fperson%2F10001) (linked from Datasette documentation), manually clicking on [the link](https://register-of-members-interests.datasettes.com/regmem-98dc8b7/people/uk.org.publicwhip%2Fperson%2F10001?_format=json) (""This data as .json"") to the json data results in an error 500 `data() got an unexpected keyword argument 'as_format'`

The [JSON page linked to from the documentation](https://register-of-members-interests.datasettes.com/regmem-d22c12c/people/uk.org.publicwhip%2Fperson%2F10001.json) however is correct (the page address ends in `.json` rather than using a query string `?format=json`)

This particular datasette demo page is now a few versions behind, but I was able to reproduce the issue using v0.29.2 and a downloaded copy of the demo database (and also with the current HEAD).

Here is a stack trace:
