Hi @samueloliver , Looks like the recent Power BI update messed with how your custom JSON theme works. Based on the errors you're seeing, it seems like the structure of the theme doesn’t match the new requirements. Here is a list of issues according to the above errors.
Type Issues: Some properties (like page) need to be an array but aren’t. The title property under categoryAxis and valueAxis needs to be a simple value like a string, number, or boolean, but something’s off there too.
Missing Stuff: Certain required properties like reverseDirection, hideText, solid, gradient, and pattern are missing in some parts of your JSON.
Extra Stuff That Shouldn’t Be There: There are properties in your JSON that Power BI doesn’t recognize anymore, so they’re throwing errors.
Schema Mismatch: For some parts, like title, Power BI wants it to fit one specific structure, but your file might have too much going on or be slightly off.
Clean Up Your JSON
Here’s what to look for:
Fix Property Types: Make sure things like page are arrays and title is a string, number, or boolean.
Add Missing Properties: If Power BI says it needs properties like reverseDirection or solid, add them in.
Remove Extras: Delete any properties that Power BI doesn’t seem to like anymore.
Here’s a quick example of what a fixed section might look like:
{
"visualStyles": {
"*": {
"*": {
"categoryAxis": [
{
"title": "Example Title",
"reverseDirection": false,
"hideText": false,
"solid": true,
"gradient": null
}],
"valueAxis": [
{
"title": "Value Axis Example",
"reverseDirection": false,
"hideText": true,
"solid": true
}]}}}}
If this doesent work out, you can share the json file itself and we can definitely take on from there.
