Power BI Custom Visual Error Embedded for Customers

[ejQap]

Hi, since yesterday, we have been experiencing a rendering issue with a custom visual in our application that uses Power BI Embedded for customers.

Our custom visual works fine in Power BI Desktop and in Power BI Embedded for our organization. We haven’t updated or changed our custom visuals for a while, so this issue seems to have occurred without any recent modifications on our end.

Has anyone else experienced this issue recently? Any insights into potential causes would be greatly appreciated.

Note:

We faced a similar problem last year, where the custom visual failed to render in both the embedded for our organization and for customers.

Hi @ejQap ,

Thank you for reaching out to the Microsoft Community Forum.

This error typically arises when a custom visual cannot be properly rendered in Power BI Embedded reports.

Few potential causes and things to check:

1. Power BI Service Changes: Microsoft occasionally updates the Power BI service backend, which can unintentionally break compatibility with some custom visuals, especially in embedded contexts. Since you didn’t make any updates, this is a likely cause.

Note: Check the Power BI support page or the Power BI community forum to see if others have reported similar issues recently.

2. Visual Capabilities or API Version: Even if the visual hasn't been modified, an outdated apiVersion or unsupported capability in your custom visual’s manifest can cause issues in Embedded scenarios.

Note: Double-check the pbiviz.json file of the custom visual. Ensure it uses a supported API version (ideally v3.8.0 or higher). Compare it with the latest custom visual guidelines: Custom Visual Guidelines –-> Microsoft Docs.

3. Token Issue: Sometimes token mismatches, authorization changes, or domain policy updates can affect how visuals are rendered in embedded environments (especially for customer-embedded reports).

Note: Confirm the access token being used is valid and scoped correctly. Check browser console logs for CORS or authentication-related errors. Make sure any Content Security Policy headers aren’t blocking resources.

4. Power BI Visual Configuration: There may be a configuration in your embedded report setup or iframe code that prevents certain custom visuals from initializing correctly.

Note: Check your embedded report iframe settings. Ensure loadCustomVisualsFromAppPackage or loadCustomVisualsFromExtension (depending on how you're embedding) is configured properly.

Hi @v-dineshya 

Thanks for sharing the potential solutions.

Unfortunately, we have explored all the options but haven't had any luck.

We are currently working with the Microsoft support team to resolve this issue.

Note:
1. The custom visual was created using an R script.

2. We faced a similar issue last year (September 2024) where the custom R visual worked fine in Power BI Service, Desktop, and Embedded for Organization, but not for customers. Microsoft eventually fixed it and stated that the issue was due to a bug in R script visuals.
