Error while uploading table.
I am using Pro plan and I am getting the below error. Total KB sources are 16 and 4822 total rows across the knowledge base. Error: "406 - "{"message":"The number of rows in the uploaded table exceeds the limit for your current plan. Please upgrade your plan to upload tables with more rows.","statusCode":406,"statusText":"Not Acceptable","timestamp":"2025-08-11T22:35:22.083Z","path":"/v1alpha1/public/knowledge-base/document/upload/table?overwrite=true"}""

Hey there! 👋
That 406 message is letting you know you’ve hit the table-row quota that comes with the Pro workspace:
• Pro plan limit → 5 000 total table rows across all knowledge-base table sources in the workspace.
You’re already sitting at 4 822 rows, so any upload larger than 178 rows will push you past the cap and the upload is rejected with the 406 – “number of rows … exceeds the limit for your current plan”.
How to move forward:
1. Trim the sheet you’re uploading to ≤ 178 rows, or
2. Delete/merge existing table sources to free up space, then re-upload, or
3. Upgrade the workspace to the Business tier (1 M table-row limit) if you need to store more than 5 000 rows long-term.
You can check the plan limits any time here → https://docs.voiceflow.com or on the pricing page https://www.voiceflow.com/pricing 😊
Hope that clears things up – let me know if there’s anything else I can help with!
