Is anyone else experiencing this? Does anyone else have a solution or workaround? I can't make changes to the exising report and I can't publish and push it through the pipeline because of this error.

Hi Bron_Smith
The mid-2026 Fabric/Power BI update tightened the PBIR JSON schema validation on the Service side. The Git-integration importer now rejects any property that isn't explicitly in its schema ("schema does not allow additional properties").
showSentenceFormat is a newly-introduced tooltip formatting property that a recent Power BI Desktop build wrote into your visual.json the last time the report was saved. It lives under the visual container's visualTooltip object as a default, so it gets written even though you never configured tooltips. The Service's schema hasn't caught up to accept it yet, so the import fails.
Try this workaround in your GitHub repo:
- Search the repo for showSentenceFormat.
- Delete that property everywhere it appears in visual.json files (also remove showTooltipFieldsOnly, showValuesInBold, showActionsInTooltips if they show up).
- Commit → sync the workspace from Git.
If you'd rather not touch JSON: disconnect the workspace from Git, publish from Power BI Desktop, then reconnect Git.
Thank you.I'll try this. Thank you. Just frustrating as I am not using tooltips anywhere in the report.
Is it common to release report features not yet supported by the Online Service? Failing to sync/update from Git since this field is not yet recognized, which is a bit strange since the report can be saved in PBI Online with that setting. Could we raise this issue to support? The workaround is to manually set these values in the Online Editor, but that's less than practical...
