I have a list that explicitly uses the modern experience.screenshot of list experience setting

The create and edit view are also set to open in a dialog. screenshot of dialog setting

Even so, whenever I create a new list item, it opens in its own page in the classic experience. This poses a problem, as one of the required fields is a location column, and when I to fill that field and submit, I get a validation error about an Invalid JSON primitive.

Weirdly enough, the create view worked just fine through the sidebar dialog last week and I did not change anything other than a column formatting since then.

For completion's sake, this is the column formatting

    "$schema": "https://developer.microsoft.com/json-schemas/sp/column-formatting.schema.json",
    "elmType": "div",
    "children": [
            "elmType": "span",
            "txtContent": "@currentField"
            "elmType": "span",
            "txtContent": "=if(@currentField != '', 'm²', '')",
            "style": {
                "padding": "0 1px"

Is there any way I can force Sharepoint to use the dialog again? Or at least properly add my location field through the classic view?

For keeping to open with classic issue, what the column formatting you added before you found the issue?

As a workaround, you can save the list as template (include content) and create a new list to use this saved template, check if you can create new item with new experience.

For the location column issue, since location column is a new experience feature, we can only select location in the new experience. In the classic experience, I open an exiting value in location column in my environment and find the column format as below:

{"LocationSource":"Bing","LocationUri":"https://www.bingapis.com/api/v6/localentities/41c08f01-65b9-ccd4-1340-2d416e267849?setLang=en","UniqueId":"https://www.bingapis.com/api/v6/localentities/41c08f01-65b9-ccd4-1340-2d416e267849?setLang=en","DisplayName":"Chinatown, Singapore, Singapore","Address":{"City":"Singapore","CountryOrRegion":"Singapore","Street":"Chinatown, Singapore, Singapore"},"Coordinates":{"Latitude":1.2847900390625,"Longitude":103.84419250488281}}
  • The column formatting just adds a span with "m²" to a column, to properly indicate square meters. I'll add it to the question.

  • My users are very much not technical, so expecting them to add JSON content when they create an item will not work, I'm afraid. I tried out your suggestion with creating a new list from the old one, but sadly the behavior persists.
