Deeplink to file using /viewer/teams does not work in New Teams

[pheidler]

Deeplinking to a file not stored in a Channel/Shared Documents folder no longer works in New Teams. This previously worked in Classic Teams using the /viewer/teams API. See here: https://techcommunity.microsoft.com/t5/teams-developer/how-to-open-a-file-in-the-custom-spfx-teams-tab-in-ms-teams/m-p/1786898/highlight/true#M2003

Hi @pheidler - Could you please let us know which deep link format you have used to navigate to file?

[pheidler]

@Prasad-MSFT Yes, like this:
https://teams.microsoft.com/_#/${document.FileType}/viewer/teams/${document.Url}?threadId=${channelId}&baseUrl=${siteUrl}&fileId=${document.FileUniqueId}&ctx=files&viewerAction=view

[Prasad-MSFT]

Hi @pheidler - Could you please let us know from where you got this deep link to file format? Because in the official documentation the format is suggested as:
https://teams.microsoft.com/l/file/<fileId>?tenantId=<tenantId>&fileType=<fileType>&objectUrl=<objectURL>&baseUrl=<baseURL>&serviceName=<Name>&threadId=<threadId>&groupId=<groupId>

Also please do share your complete deep link which you used, (as from the syntax it's not quite clear) so that we can form a similar deep link at our end.

@Prasad-MSFT This was advised by someone with MSFT support in this thread: https://techcommunity.microsoft.com/t5/teams-developer/how-to-open-a-file-in-the-custom-spfx-teams-tab-in-ms-teams/m-p/1786898/highlight/true#M2003

The official documentation refers to opening links to files in a channel, but doesn't mention files stored in other SharePoint folders.

This is the complete deep link: https://teams.microsoft.com/_#/pdf/viewer/teams/https:~2F~2F[tenant_name].sharepoint.com~2Fsites~2FMark8ProjectTeam2~2FMeetingPack_4~2FAgendaDocuments~2F[file_name].pdf?threadId=19:082b34f4abf84eacbcef8ac5d0a923db@thread.tacv2&baseUrl=https:~2F~2F[tenant_name].sharepoint.com~2Fsites~2FMark8ProjectTeam2~2FMeetingPack_4&fileId=b3eaa820-75ee-4f2b-8b44-5fa60c848789&ctx=files&viewerAction=view

Thanks!

@Prasad-MSFT Yes, like this: https://teams.microsoft.com/_#/${document.FileType}/viewer/teams/${document.Url}?threadId=${channelId}&baseUrl=${siteUrl}&fileId=${document.FileUniqueId}&ctx=files&viewerAction=view

@pheidler If your file is not stored in any channel, where is it stored in SharePoint? and which thread/channel id are you using in the deeplink Url which you shared?

This is the only supported deep link format for configuring a deep link to connect to a file in a channel:
https://teams.microsoft.com/l/file/<fileId>?tenantId=<tenantId>&fileType=<fileType>&objectUrl=<objectUrl>&baseUrl=<baseUrl>&serviceName=<Name>&threadId=<threadId>&groupId=<groupId>
https://learn.microsoft.com/en-us/microsoftteams/platform/concepts/build-and-test/deep-link-teams#generate-deep-links-to-a-file-in-a-channel

There is no deep link format available in official documentation for files stored outside team's channel.

@Prasad-MSFT It's stored in the backing team site. The channel ID is from the Teams tab context. We use this feature to display documents that are managed through our SPFx app and stored in a separate folder than Shared Documents. If this is not currently supported, can we expect this feature to be added at some point? This is a key feature for us that the switch to New Teams has removed.
