Custom Themes

[HaiVN]

Hello community,

I am importing a json thema to my Power BI report and It shows message: '#/ must NOT have additional properties (additionalProperties; matching schema #/additionalProperties)'. I am wondering if some one has the same problem and how can I can fix it? 

I have read this"Solved: Re: Custom themes are broken - Microsoft Fabric Community" , and I have fixed several bugs, but I do not understand what are the problems with 'title' and 'header'

Thank you!

Hi @HaiVN ,
Based on the information you provided, the error you encountered when importing JSON topics in Power BI, "#/ must NOT have additional properties (additionalProperties; matching schema #/ additionalProperties)" indicates that there is a problem with the JSON structure you are trying to import. additionalProperties)" indicates that there is a problem with the JSON structure you are trying to import. Specifically, the error message states that "title" and "header" must NOT have additional properties and that the matching schema (additionalProperties; matching schema #/additionalProperties) for "title" and "header" is the same as the one for "additionalProperties". " matching schema.
To resolve this issue, you need to make sure that the "title" and "header" in your JSON data do not have additional properties beyond those defined by your schema. If you are using a specific schema or data model that defines these as keys, then they should only contain attributes that are allowed by that schema.
For example, if your schema specifies that "title" can only have "fontSize", "fontFace" and " color" as attributes, then adding any other attributes to "title" in your JSON will result in an error. The same is true for "header".
Please check that your JSON data matches your schema and remove any extra attributes from the "title" and "header". Once you have corrected the JSON, you should be able to successfully import it into Power BI without receiving this error message.
You can try to find the code that specifies these tags so that you know the format of the code.
