Error when executing the POSTTRAN job in CardDemo Blu Age modernized application

Question

In AppStream, the execution of the POSTTRAN job fails at STEP15 with error code 35. I get this stack trace:

Accepted Answer

By default, AWS Blu Age Transformation engine applies the following dataset conversion mapping:

* GDG are converted to a collection of files on the file system
* VSAM ESDS are converted to bluesam datasets
* VSAM KSDS are converted to bluesam datasets

But we need to end up with VSAM ESDS as files on the file system. In order to do that, you must change the result of the generation of the Groovy Script using the ESDS:

* bluesam(“...”) needs to be changed to fileSystem(“...”)
* dataset(“...”) needs to be changed to path(“...”)
