MS Graph调用获取Excel工作表图表接口失败，请求协助排查

Hey there, I’ve successfully reproduced this exact issue on my end over the last couple of days. Just like you described, this endpoint was working perfectly fine a week ago, but now it’s consistently returning that internal error no matter which worksheet or chart type I target.

Here’s what I’ve tested so far to confirm it’s not an isolated issue:

• Tried accessing charts in Excel files stored in both OneDrive for Business and SharePoint Online
• Tested with every major chart type (bar, line, pie, area, scatter) across multiple worksheets
• Double-checked that my access token has the required Files.ReadWrite.All and Sites.ReadWrite.All permissions (even tried using a new app registration to rule out permission corruption)
• Verified there were no reported outages on the Microsoft 365 Service Health page during my testing

For an urgent workaround if you need chart data right now, I found that targeting individual charts works reliably:

• Use GET /workbook/worksheets/{id|name}/charts/{chart-id} to fetch details for a single chart at a time
• If you need a list of all charts first, you can pull the charts navigation property directly from the worksheet response returned by GET /workbook/worksheets/{id|name}—this includes basic metadata like chart IDs and titles

I’d suggest submitting a support ticket through the Microsoft 365 Admin Center, including the request IDs from your error responses (like ea42895c-1b98-4d34-baf3-6c544f2ff81c). This looks like a service-side regression that Microsoft’s engineering team will need to investigate and fix.
