SUPPORT / SAMPLES & SAS NOTES
Problem Note 70917: SAS® Model Studio on SAS® Viya® 3.5 increases the string length configuration to support the importing and exporting of larger projects
 |  |  |  |  |
For SAS® Visual Forecasting and SAS® Visual Data Machine Mining projects, you can import or export projects via the SAS Serialized Transfer command line interface. However, there is currently a string value limit of 20MB. To import and export projects via this command line interface, you need to change the code to remove the Jackson object mapper maxStringLength setting.
If you try to import a SAS Model Studio project from one environment to another, the import fails abruptly. When this issue occurs, the /opt/sas/viya/config/var/log/analytics-services2/default log contains an error similar to the following:
