Can't GetRoomLists

I'm trying to create something similar to the Book a Room template app, but I'm not getting very far. I am trying to get a collection of rooms to fill of our organizations conference rooms. I copied some code from the Book a Room app, but I keep getting a blank collection. Any advice is greatly appreciated.


Code, run at app start:

ClearCollect(AllRooms, Office365.GetRoomLists().value);


Data Sources:



Responsive Resident

Hi Jlevwayside, DId you get a chance to check the data source does that have data? Regards, Pavan Kumar Garlapati

It is the same data source as in the Book a Room template app. That app can retieve the room list successfully.

Hi @jlevwayside ,

This formula is right.

I've made a similar test and not the same problem like your description.871.PNG






If you have no items in there then check the Connector and make sure the user chosen can access the Room List.

Here's a similar isse for your reference:

@v-yutliu-msft Your method worked once I tied it to a button. It does not work if I have it in the "App" object within the "OnStart" hook. I would like these loaded at the start of the app, is that possible?


It also does not seem to work with the OnVisible section of a screen.
