Hello @Fcastineiras,
Thanks for raising this. I cannot see any mention of class ProcessInstanceModificationBuilder in the stack trace you provided, maybe you could share a more complete log file. Could you also provide an example of a code snippet that was successfully ran ProcessInstanceModificationBuilder.execute() in 7.16 but not in 7.19? This could help reproduce and analyze the issue.
