I have a task that sets user variable to {LOGIC(If|Integer|{TASK(0dd9aed2-9db3-43ea-801d-dd827c6ef92e|ExitCode)}|==|0|0|)}

This task has worked fine for years, but now I'm getting this error:

Unhandled error in SetVariable: System.Exception: Variable object types mismatch
at VisualCronService.ProcessTaskVariableSetClass.ReadServer() in C:\git\code\VisualCronService\Jobs\TaskProcesses\Internal\Variables\clsProcessTaskVariableSet.vb:line 87

The Task ExitCode value referenced by the variable is: 0
