I am trying to settings methods as of pages in my application for configuration of urls, to update theme and for multiple functionalities but whenever i am using page.config or getConfig or setConfig. I am always getting this error. because of this error I am not able to work on application. There is no clear solution in google also which can help to resolve.

Please Help me resolve this issue. I found one similar issue but it says by contentUrl in manifest, we can fix but I have no idea how it can be fixed. I tried as per document to create a base URL but still getting the same error.

Hi @MOD Administrator

Teams tag is mainly focused on the general issue of Microsoft Teams troubleshooting. According to your description, your question is related to Teams Development which is not in our support scope. To better help you solve your problem, I will add the Teams Development tag to your post. Thanks for your understanding and patience!

Hi Team,
Here is one of the code which is producing the error mentioned above-

 app.initialize();
    app.getContext().then(() => {
      pages.config.registerOnSaveHandler(
        (saveEvent: pages.config.SaveEvent) => {
          let url = `${sHostname}/${generateUrl}`;
          let tenantId = window.location.hostname;
          if (configState.bSSO) {
            const bydAuth = `${window.location.origin}/sap/ap/ui/${Util.ABAP_PATH}/web/byDTeamsTab/abap/auth.html`;
            url += `&bydAuth=${encodeURIComponent(bydAuth)}`;
          } else {
            tenantId = tenantId.replace("-sso", "");
          }
          pages.config.setConfig({
            contentUrl: url,
            websiteUrl: url,
            suggestedDisplayName: configState.tabName,
            removeUrl: `${sHostname}/byDTeamsTab/remove.html?theme={theme}`,
            entityId: tenantId,
          });
          if (configState.bMandatoryFieldFilled) {
            saveEvent.notifySuccess();
          } else {
            saveEvent.notifyFailure();
          }
        }
      );
    });

It seems like you're encountering an initialization error with the Microsoft Teams SDK. The error message suggests that the SDK is not properly initialized before calling setConfig. Ensure that app.initialize() is called at the start of your app's script execution and that it completes before any other SDK methods are called.

Here's a revised version of your code snippet to help illustrate this:

app.initialize().then(() => { // Now that the SDK is initialized, you can use the SDK methods app.getContext().then(() => { pages.config.registerOnSaveHandler((saveEvent) => { // Your existing code logic }); }); }).catch((error) => { // Handle any errors that occur during initialization console.error("Microsoft Teams SDK initialization error:", error); });

Make sure that app.initialize() is not nested inside any other function that might delay its execution. It should be one of the first things your app does. If you still encounter issue or have further questions, please let us know. So, we will look into it and let you know the updates.

Hi @Dinesh Rajagoni (Tata Consultancy Services Limi)

inside useEffect hook, app.initialize() method can be called?

in below code it's being called-

// useEffect(() => {
  //   app.initialize().then(() => {
  //     const contextPromise = app.getContext();
  //     contextPromise.then((context: app.Context) => {
  //       pages.getConfig().then(() => {
  //         updateTheme(context.app.theme);
  //         Util.switchLanguage(context.app.locale);
  //         // pages.config.setValidityState(true);
  //         app.notifySuccess();
  //       });
  //     });
  //   });
  //   const sHostname = Util.getQueryVariable("hostname") || "";
  //   app.initialize().then(() => {
  //     app.getContext().then(() => {
  //       pages.config.registerOnSaveHandler(
  //         (saveEvent: pages.config.SaveEvent) => {
  //           let url = `${sHostname}/${generateUrl}`;
  //           let tenantId = window.location.hostname;
  //           if (configState.bSSO) {
  //             const bydAuth = `${window.location.origin}/sap/ap/ui/${Util.ABAP_PATH}/web/byDTeamsTab/abap/auth.html`;
  //             url += `&bydAuth=${encodeURIComponent(bydAuth)}`;
  //           } else {
  //             tenantId = tenantId.replace("-sso", "");
  //           }
  //           pages.config.setConfig({
  //             contentUrl: url,
  //             websiteUrl: url,
  //             suggestedDisplayName: configState.tabName,
  //             removeUrl: `${sHostname}/byDTeamsTab/remove.html?theme={theme}`,
  //             entityId: tenantId,
  //           });
  //           if (configState.bMandatoryFieldFilled) {
  //             saveEvent.notifySuccess();
  //           } else {
  //             saveEvent.notifyFailure();
  //           }
  //         }
  //       );
  //     });
  //   });
  // });

Hi @Robin Sheng-MSFT

issue is not fixed, tried above solution and kept the code in different code blocks and pages.config.registerOnSaveHandler function is not allowing to use in any other context except settings which is depcricated when we try to use in code
