When calculating tax an error from Avalara is received, indicating an error happened. The error message looks like:
"Internal Error in GenerateAvaBatchUpload: AvaBatchUpload Encountered an Internal Error: BatchSave for file Zuora_BR-..."
This error can happen in both the Avalara-built and the Zuora-built integration.
This can be caused by a variety of issues. To resolve it, calculate tax again.
In the Avalara-built integration, use the manual bill run page to recalculate the bill run.
In the Zuora-built integration, you will most likely need to recreate the bill run, since the original may have been canceled.
Should the issue persist after multiple recalculations, please contact Avalara support.
