Canvas Apps stange behaviour

Hi All,

Is anyone experiencing any strange behaviour when using and editing their canvas apps? for example, whilst in edit mode I can see the list of items in the gallery, but the published version shows as blank. I'm using SharePoint as a datasource and have been using the app for 8 months without any problems. Also, this morning (17/05/2024 UK time) I also saw two errors, unable to retrieve data and one about a Power Platform will start relying on a new cloud service dependency called Power Platform API, evaluate adding the service to your Conditional Access policies, and updated URLs to your firewall rules.

I've reported this to our IT Service desk to investigate, but they think it could be related to connecting to our O365 tenant. It seems to be very slow to retrieve data and seems generally slow more recently.

I'm just trying to establish if this is unique to us, or is anyone else experiencing similar issues.

Thank you

Derek

Hi,

The only time I've experienced strange behaviour was when i used experimental features which were changed in the meantime, good example was Formulas, which i absolutely loved since day one and I've used them heavily in one app when in exp mode still, and there was a moment when formulas got broken and the massive problems started...

PS. the API note I've had quite a while ago.

I do have a mix of experimental controls .eg. combo boxes, tet inputs etc. but I have been using them around 6 months or so. I did copy some of the controls from a Teams version of a canvas app and liked them as you had more control over the properties. I started using Formulas about a month ago but only on very basic configuations.
Thanks for you reply.
Derek

one more thing about the missing items in gallery,

Happened to me when i was testing the screen and i started by putting clearcolllect into a button so i can click to test, but the plan was to place that code in onvisible of the screen, I then forgot to place it there deleted the button and had the empty collection (collection was still present because of clearcollect in other places so no errors).

I found that it's good to have a debug menu to fix this kind of issues, I usually place a bug icon somewhere and put my entraid check on visible, then you can populate container (shown by clicking the bug) with all sort of useful stuff : labels displaying the value of the variables, countrows of collections etc) this will help diagnose a lot of stuff after you publish your app.
