Ambiguous Error Message: Script Runtime Error statement execution failed with status: error

[tuckbrit]

I have a custom python visual in a published report that has recently stopped working. I have confirmed that the visual still works with a local version of python 3.7.7 with all packages aligning to the versions listed here: https://learn.microsoft.com/en-us/power-bi/connect-data/service-python-packages-support.

The visual has been working for roughly 8+ months without a single issue or change and i noticed today (3.17.2025) that it no longer works and i am receiving a error message that does not help me at all "Script Runtime Error --> statement execution failed with status: error". Is anyone else experiencing this or aware of any known issues that could cause this?

@Deku Thank you for the context of the plan to upgrade. I believe it was and the documentation is out of date. Another person on my team was running into the same problem and upgraded from matplotlib 3.2.2 to 3.5.0 on our local version of python (3.7.7) and we could recreate the issues. Turns out that the "b" keyword argument to plt.grid() was deprecated in version 3.5.0 and changed to "visible". Once changed in the custom python visual, the report was no longer experiencing issues.

Hi @tuckbrit ,

Thank you for reaching out to the Microsoft Fabric Community. Also @Deku  and @lbendlin  for your inputs and actively participating in the community forum and for the solutions you’ve been sharing in the community forum.

To resolve your issue with the custom Python visual in Power BI Service, first, ensure that your script only uses Power BI Service-supported Python packages by checking the latest list here.

Next, test whether Python execution works at all in Power BI Service by running a simple script like print("Hello World"). If this fails, the problem may be with Power BI’s execution environment. Additionally, try re-publishing the report from Power BI Desktop after confirming the visual works locally, as this can refresh dependencies and resolve potential conflicts. Also, check if there have been changes to the dataset, such as missing values or new column types, which could cause execution failures.

Since Power BI Service has execution limits on memory and processing time, consider optimizing your script if it processes large datasets. If none of these steps resolve the issue, you may need to open a Microsoft support ticketas mentioned by @lbendlin .

I hope my suggestions give you good idea, if you need any further assistance, feel free to reach out.

There was a plan to upgrade python

Maybe finally happened. Not seen anything about it since that blog post though
