[Incident] - Send Now and Page Download Bug
Customers using ‘Send Now’ on a published version of a workbook were unable to generate an export, and instead received an error, Error Message: corrupt uuid: 0 (HTTP null).
A code change was made on May 15, 2023 at 5:22 PM which allowed users to select the desired workbook version for export, causing published versions to have incorrectly set workbook IDs. This resulted in impacting the “Send Now” functionality, causing it to pass incorrect values, present errors, and fail export generation.
All customers using Send Now on the published version of a workbook between May 15, 2023 at 5:22 PM and May 16, 2023 at 9:30 AM were affected and would receive the error: Error Message: corrupt uuid: 0 (HTTP null).
The first instance of the incident was reported to Sigma Support on May 16, 2023 at 6:29 AM. Our immediate mitigation was to advise affected users to use scheduled exports rather than use ‘Send Now’, as scheduled exports were not susceptible to this issue.
On May 16, 2023 at 9:30 AM the fix was deployed, resolving the incident and fixing the issue for affected users.
To prevent future issues from occurring in this regard, we are adding additional checks to our frontend tests to ensure validity before communicating with the backend, and also adding additional internal alerting to the backend if such errors occur. We are also adding additional tests in our deployment system that will check that workbook IDs cannot be set to an invalid state.
We sincerely apologize that this happened, however we are here to help the impacted customers in every way possible. In case you may have any questions don’t hesitate to contact your Sigma Customer Success Manager, Sigma Live Chat, or email@example.com (for Security-related concerns).
