When we try to export application it couldn't complete and waits at 99%
Sometimes export of application fails due to corruption of flows in application, also rename or removal of flow is not possible.
Uncaught Exception in Thread AWT-EventQueue-0 , null java.lang.NullPointerException
To fix the problem and enable the export, perform the following steps :
Verify the flow which is corrupted
Perform the following steps on nolio database
1. select id from executable where name = ‘<FLOW NAME’>;
this will find a VALID id for the relevant flow
2. select * from executable_instances where delegate_id NOT IN (select id from executable);
take the delegate_id from this query output
3. update executable_instances set delegate_id = ‘<VALUE FROM 1st QUERY>’ where delegate_id = ‘<DELEGATE_ID FROM 2nd QUERY>’;
Remove the flow and Verify the export.
Note: Before making any modifications, please take a backup of database. Contact support if you need further information.
