Local fix

  • To workaround the issue, you can duplicate the set of rules
that is being used in multiple places into another package to
prevent the engine sharing between the two tasks.
You will then be able to perform the export.

Problem summary

  • Incorrect translation for working memory attributes using lead
to this exception

Problem conclusion

  • the code is fixed

Temporary fix
