Office-js: Add-in Error We couldn't connect to the catalog server for this add-in.

[ndeeH]

Hi there,
we are getting this error:
Add-in Error We couldn't connect to the catalog server for this add-in.
when we switch our PowerPoint Content Add-In into Presentation Mode!

When we are NOT in presentation mode - our content add-in works as desired.
The manifest is deployed via O365 Admin Center...

_Any ideas why getting this? Please help - we are failing store validation because of this!_

TIA, Andi

[ndeeH]

To ensure it is not a problem in my add-in - I removed everything from my add-in.
Now I have only a plain HTML page and I also get this error in presentation mode of PowerPoint Online:

_Any ideas?_

[JuaneloJuanelo]

i wonder if you can provide a copy of your manifest so we can try it internally?
Also please share more details on what verision and Office builds and platforms you are experiencing this.

@JuaneloJuanelo
Hallo Juan, thank you for responding on my issues.
We are currently failing at store validation of our add-in and do not come any futher....

All issues have to do with the online version of PowerPoint in presentation mode.
I tested in this versions Chrome (67.0.3396.99) and also tried latest Firefox (61.0.1 64-Bit) - same problems.
To test the add-in with PPT Online we are using the Office 365 Admin Center to upload the manifest.

1. Upload the Manifest to O365 via Admin Center
2. Open PPT Online (with O365 Account)
3. Insert Add-In -> works
4. Switch to presentation mode:
   

Another try was to directly upload the manifest into PPT Online (Office Add-In Dialog / Upload my add-in). There I get a different error in presentation mode:

We are seeing those errors in console which we are not able to associate with failures in our add-in:

Failed to load https://euc-powerpoint.officeapps.live.com/pods/RemoteUls.ashx?waccluster=NL1: 
The 'Access-Control-Allow-Origin' header contains multiple values 'https://contentstorage.osi.office.net, https://contentstorage.osi.office.net', 
but only one is allowed. Origin 'https://contentstorage.osi.office.net' is therefore not allowed access.

and

OSF_Outil_getQueryStringParamValue: The parameter is not found.
OSF_Outil_getQueryStringParamValue: The parameter is not found.

_Hope you could help us - our customers are waiting to use the store version of this add-in._

TIA, Andi

@weird-dreams thanks for the detail, we'll take a look.

@JuaneloJuanelo Any news on this?

[ndeeH]

@JuaneloJuanelo Did your developers find anything why we are getting the error:
Add-in Error We couldn't connect to the catalog server for this add-in.

[JuaneloJuanelo]

Apparently there is a bug we are still investigating.

[ndeeH]

Hallo @JuaneloJuanelo ,
any news on this? For the current store validation our add in must work in PowerPoint Online in presentation mode. Here we are facing bugs which are not originated in our add in.
We could show a page "Add in not supported in PowerPoint Online" - but I think this will not pass validation. (There is no requirement set that will hide the add in in the online versions)
Any ideas?
TIA, Andi

Hallo @JuaneloJuanelo ,
this issue is still present just tested again in PowerPoint Online in newest Chrome Version.
When using the manifest earlier we get the error:
We couldn't connect to the catalog server for this add-in.

I have also seen a new bug - this might have to do with my thumbnail issue #184
When scaling content add ins there seems to be a overlay bitmap AND the content that scales differently:

This also happens with many content add ins which are already in the store.

_Please let us know, when we could test again.
I will try to get our add in through store verification and mention those open bugs here....
(Are you in contact with the verification team?)_

TIA, Andi

[ndeeH]

@JuaneloJuanelo Unfortunately - I tested with a wrong manifest - this issue is still present. :(

With the manifest of our QA version this issue has gone.
The add ins and azure settings are identical. Only the deployment goes to a different azure subscription.

[LiXiaoooowei]

@weird-dreams I recently developed a content add-in for PowerPoint and faced the same wierd issue with PowerPoint online version. May I know which azure subscription did you use to fix the issue?

[ndeeH]

@LiXiaoooowei
I tested again and it seems our add in is set to work only in the desktop versions.
It seems MS has a switch to do this, because we do not have any requirement restrictions to do so.
@JuaneloJuanelo The error still exists! May the store verification set to only support the desktop versions?

When we create our content add in the desktop version and open it via OneDrive in PPT online - then we get these notifications (always clicking on first button):

[kbrandl]

@JuaneloJuanelo are you able to provide any update on this issue? FYI, seemingly related issue #302 contains steps to repro this issue.

[nirorlev]

@JuaneloJuanelo We're also experiencing the same issue on a different add-in that we develop.
If you need another add-in code for debugging this - I can share ours.

[ndeeH]

@nirorlev Your error message seams different from mine "_..couldn't connect to the catalog server..._".
Is there an exception outside of your code which leads to this error when switching to presentation mode?

[JuaneloJuanelo]

guys i was able to repro this issue, it seems to only be happening when side loading add-ins and also when using corp catalog.

[JuaneloJuanelo]

we are tracking with 2737719 we'll fix it ASAP thanks all for your feedback
