How to change theme (json) schema definitions?

[LeverPowerCLiff]

I was trying to create a theme with a custom font size, when I then load in the .json file into the report I get the error message: #/textClasses/callout/fontSize must be <= 45 (maximum; matching schema #/definitions/fontSize/maximum).

I found the github page about these report schemas here: https://github.com/microsoft/powerbi-desktop-samples/tree/main/Report%20Theme%20JSON%20Schema, but cannot find a way to force the .json file/ power BI to use my edited report theme schema I have downloaded - I get an "Error importing theme file" when I include the line "$schema: "myeditedschema.json".

Is there a way to find and edit the default schema Power BI uses or a way to force it to use a different schema such that I can use a larger font?

Many thanks.

Hi @LeverPowerCLiff ,

It seems like you’re trying to create a theme with a custom font size, but the maximum font size allowed is 45.

Edit the default schema: You can edit the default schema that Power BI uses by following these steps:

Go to the Power BI admin portal.
Select “Tenant settings”.
Under “Settings”, select “Report settings”.
Edit the default schema as per your requirement.

Thank you for your reply,

There is no report settings header or any settings refering to reports under Tenant settings.

Any advice?
