Description

I converted a PDI 9.1 project via file -> convert

When trying to open the converted Workflow I get the following error and stacktrace#

Windows Server 2008R2, Java OpenJDK 13, Hop version hop-client-0.99-20210406.151009-1

Because of critical company information in the project files I cannot attach a workflow file.
