Authentication "The requested resource does not support http method 'GET'."

[TimLam]

Hi!

Hoping someone can help shed some light on an issue currently being experienced with all of the PowerApps we have built, specifically an error message appears after authenticating for the first time and allowing the connection to SharePoint from the App stating the error below appears in the web browser (both on iPhone, iPad and Android devices) at the web address starting https://europe-001.consent.azure-apim.net/firstPartyLogin?data= (followed by a long data string")

The requested resource does not support http method 'GET'."
 

If the error is ignored the application will either hang and go no further or will open the App but the error message "An unknown error has occured" will appear when trying to do anything that involves connecting to the data source.

I have tried uninstalling and reinstalling etc but the problem keeps happening - sometimes signing out of the account and bakc in fixes it but other times it doesn't.

I can replicate this error by clicking the three dots next to an app and selecting "Use a different connection", at the "SharePoint" screen I click "Create" and after the white loading box it opens up the web address starting with https://europe-001.consent.azure-apim.net/firstPartyLogin?data= and shows the error 

 The requested resource does not support http method 'GET'."

If i then check under "Connections" in the power admin section whilst logged in as the user having problems I will see a connection to SharePoint with the correct username but it also shows another connection with the name {username}{token} with a red explaination mark saying "Update Password" (both have the apps in quesiton under the setting "Apps and flows using this connection").

The only way this error can be fixed is to then click "Update Password" and click on the username from the Micorosft login screen (it says user@domain.com is signed it) and then it start working as normal.

Please can someone provide some guideance as it's not feasible to ask the users to go into the admin centre each time and update their password in the connections setting screen.

Thanks!

Hi TimLam,

Does this error occur when shared users open the shared apps on Web browser(iPhone, iPad, Android)?

If yes, have you also shared the data source on which the app relies to shared users before you share the app?

Can shared users open the apps on PowerApps studio if they have installed one?

Per my certain knowledge, the first time shared users open the apps on their side, they will be asked to create connections to the data source using their own credentials, it won’t occur once the connections are properly connected.

Best regards,

I have the same error. App and the associated sharepoint list are both on Office 365 cloud. The Shared users are not provided option to create connections - and have to necessarily login to the web.powerapps to set their connection right.

Was this issue solved?

I have the same issue and the details are available in this post -

Mobile App not able to create connection

Any help on how previous instances were resolved.
