Power Apps: Debugging & Error Handling

By Ashwin Venugopal -

 





Introduction

Undoubtedly, there will be moments when something doesn’t function as you expect it to. This might occur while executing your application during runtime or after crafting what you consider to be the ideal formula for your control. This is a scenario that citizen developers frequently encounter, and Power Apps simplifies the process of diagnosing and resolving issues.

App Checker

There are various methods available for identifying problems or possible enhancements in your app, which are included with Power Apps by default. The initial option is to utilize the App Checker.

The App Checker is a predefined set of guidelines executed by Power Apps to assess the application you have developed. You can find it in the menu located at the top right corner of the screen, where you can choose to either run it for the first time or perform a recheck if you have already done so. The App Checker analyzes your app and categorizes it into five distinct areas that showcase enhancements and bug fixes you can implement.

Formulas

In the formulas drop-down, you will discover any problems associated with the formulas you’ve built. This feature will point out syntax errors, such as lacking parentheses, and will also flag any formulas that are likely to fail, along with the explanations for these issues. You may encounter various types of errors in this section; some will be advisory, while others may necessitate an obligatory correction.

Runtime

Runtime errors occur when the application is started or during play mode in Power Apps Studio, indicating issues such as nonfunctional controls.

Accessibility

A frequently neglected element of app development is addressing accessibility needs for users who may have visual, hearing, or physical impairments, among other disabilities that can complicate app usage. Power Apps offers features that enhance accessibility in your application, including navigation Z-Order, which enables users to navigate your app using a keyboard. You can discover a compilation of recommendations and enhancements you can implement in this area.

Performance

Problems that affect the performance of your application will be displayed here. For example, data or controls that load slowly due to how they are built during runtime, or “loops” and features that malfunction because of the way certain elements in your app are handled.

Data Source

Here, you will find a list of data sources that may have been deleted or changed since the time your app was first built. You may have controls and functionality in your app that points to data sources that may need adding, changing or fixing.

IntelliSense

Error handling is also addressed throughout the development phase in Power Apps. A typical place where errors and bugs are likely to occur is within the formula bar. IntelliSense can identify and indicate any mistakes you might have made. This could be due to a number of reasons including a mismatch of data types (e.g. The formula expected a record, and you provided a table). It could also be due to a syntax error (e.g. Expected a “)” at the end of the formula).

Conclusion

We have successfully learnt about various ways of debugging and error handling in Power Apps.

  About If you are experiencing problems with the Microsoft Purview Information Protection scanner, check the health of your deployment by utilizing the Start-ScannerDiagnosticsPowerShell cmdlet to start the scanner diagnostic tool. The diagnostics tool checks the following details and then creates a log files with the results: Whether the database is up to date. Whether network URLs are accessible. Whether there's a valid authentication token and policy can be acquired. Whether the profile is defined in the Azure portal. Whether offline/online configuration exists and can be acquired. Whether the rules configured are valid.  The Start-ScannerDiagnostics command does not perform a comprehensive check of prerequisites. If you encounter problems with the scanner, you need to verify that your system meets the scanner's requirements, and that your scanner's configuration and installation are finished.  Verify Scanning Details Per Scanner Node and Repository Run the Get-ScanSt...

How AMI Store & Restore Works?

By Ashwin Venugopal -

  CreateStoreImageTask The CreateStoreImageTask API stores an AMI as a single object in an S3 bucket. The API initiates a task that collects all the data from the AMI and its associated snapshots, subsequently using an S3 multipart upload to store this data in an S3 object. It gathers all elements of the AMI, including most of the non-Region-specific metadata and all EBS snapshots included in the AMI, and consolidates them into a single object in S3. During the upload process, the data is compressed to minimize the space utilized in S3, which means that the S3 object could be smaller than the total sizes of the snapshots in the AMI. If the account making this API call has access to AMI and snapshot tags, they will be retained. The S3 object shares the same ID as the AMI, except it has a .bin extension. Additionally, the S3 metadata tags for the object include the AMI name, AMI description, AMI registration date, AMI owner account, and a timestamp indicating when the store operation...

Create A Store Image Task

By Ashwin Venugopal -

  Introduction When you save an AMI in an S3 bucket, a task for storing the image is initiated. This store image task allows you to track the progress and result of the procedure. Securing your AMIs It is crucial to verify that the S3 bucket is set up with adequate security to protect the content of the AMI and that this security is upheld for the entire duration that the AMI objects are stored in the bucket. If this cannot be achieved, it is advisable to refrain from using these APIs. Make sure that public access to the S3 bucket is prohibited. It is suggested to activate Server-side encryption for the S3 buckets where you keep the AMIs, even though it’s not mandatory. When AMI snapshots are transferred to the S3 object, they are sent over TLS connections. It is possible to save AMIs that contain encrypted snapshots; however, the snapshots will be decrypted during the storing process. Identify the source AMI used to create a new Amazon EC2 AMI You can determine the AMI that was us...
