Issue with Hovercard displaying text from multi line column type

[Baldo1060]

Hi all,

I've been attempting to use the example from 

List-Formatting/view-samples/horse-crests at master · pnp/List-Formatting · GitHub

to setup a Hovercard in the view formatting on a Microsoft list to display the text from a specific column but it seems to have an issue with multi line text columns.

History - I tried initially just adapting that code from above and ran into the issue that although I could see the Hovercard appear it wasn't displaying any text (from a multi line column, not rich text), I then created the solution precisely per Github and youtube vid and used the exact JSON and it had the same issue,  it seems to work if I specify the $Title column in both instances though, and I then created an additional single line text field and this worked.

I'll paste the examples JSON below, sorry about the length, can anyone confirm what's going on here? They appear to use a multi row column type in the demo?

Thanks all

@Baldo1060 Can you check if you are using correct internal name of your multiple lines of text column? It is required to use internal name of column in JSON formatting.

Check this article to find the internal name of your SharePoint column: How to find the Internal name of columns in SharePoint Online?

Hi, definitely using the internal name, the column names are simple and internal names have been created the same, only column not so is the $Title column which has a different display name.

Thanks for the suggestion but not an issue that I can see in this instance.

Ahhh, curse my fat thumbs :) Looks like it is the issue, I checked the column name in the edit column settings and although I have the correct name displayed on the column the URL does indeed tell a different story.

I guess I fat thumbed it on the initial creation and corrected it, and then forgot about it.

I blame tinkering under the influence of a glass of wine or two.

Thanks a lot @ganeshsanap for making me take a closer look.
