When the scenario definition exceeds the allowed size, the following error may appear:
Error!
Maximum size limit for the version history has been reached. The size of this version is 16.XX MB, which is higher than max. limit (16.00 MB). Please reduce the definition size to persist version.
This error occurs because the system maintains the current and previous scenario versions for comparison. The total combined size of these two versions must not exceed 16 MB. As a result, the practical size limit for the current version is approximately 7.9 MB.
Recommendations
To avoid exceeding the size limit:
- Keep the current scenario definition below 7.9 MB to ensure both versions can be stored.
- Use HTML blocks to store reusable or large content. These blocks don't count toward the scenario definition size and help reduce the overall footprint.
- Limit the number of nodes in a scenario. Scenarios with many nodes—especially more than 100—are likelier to reach the size limit. Ideally, keep their number below 30 to avoid possible loading issues.
These guidelines allow scenarios to be saved and versioned reliably without exceeding the platform limit.
