[TO BE CLOSED] [Hadrian] Multiple errors in "Tutorial 4: executing a model in Hadrian-Standalone"

[stemar87]

Following the tutorial using latest Hadrian release 0.8.1 (thus, jar file hadrian-standalone-0.8.1-jar-with-dependencies.jar) results in multiple errors:

• when issuing command "java -jar hadrian-standalone-0.8.1-jar-with-dependencies.jar -i json -o json ... " error "Exception in thread "main" com.opendatagroup.hadrian.errors.PFASyntaxException: PFA syntax error at JSON line:col 1:2: PFA engine must be a JSON object, not start of array ("[" character)" pops-up
• if trying scala version by calling "val engine = PFAEngine.fromJson(new java.io.File("myModel.pfa")).head" in scala REPL error same as above.

[UPDATE] Can be closed, issue solved by adding code to handle missing values, my bad.
