Agenda Group not working with drools 8.29.FINAL version - drools

Question

We have java rules service microservice & Using drools 7.X version to process the dynamic rules process. business rules (.xlsx) file using the Agenda-groups which is working fine.
After upgrading to drools 8.29.FINAL. kiesession.getAgenda().setAgendaFocus("1") is returning null.
NOTE :
Drools 7.49 is giving me list of agenda's
kieContainer.getKieBase().getKiePackages().parallelStream()
.forEach(obj -> obj.getRules().stream().forEach(innerObj -> {
agendaGroups.add(KieRuleMetaData.builder().agendaGroup(((RuleImpl) innerObj).getAgendaGroup())
.ruleName(innerObj.getName()).build());
}));
After upgrading to 8.29.FINAL - it's notworking
Appreciate if any help
As per the documentation, changed only drools version on pom.xml file.

Without some reproducer, it is difficult to support you effectively; next time kindly consider providing a reproducer (on GitHub for example) and share it here or via mailing-list on drools-usage or kogito-development
To me, this snippet returns as expected the agenda-group(s) defined in the rules, using 8.33.0.Final in this little reproducer here: https://github.com/tarilabs/demo20230212-so75416633/blob/main/src/test/java/org/drools/demo/RuleTest.java#L32-L34
kContainer.getKieBase().getKiePackages().stream().forEach(obj -> obj.getRules().stream().forEach(innerObj -> {
LOG.info("Rules contain this Agenda group: {}", ((RuleImpl) innerObj).getAgendaGroup() );
}));
I've used some simplified logging as you didn't provide details of KieRuleMetaData in your snippet, but as you can see with rules defining
rule "will execute per each Measurement having ID color"
agenda-group "mygroup"
when
...
The snippet above correctly prints:
2023-02-12 10:51:45,868 [main] INFO Rules contain this Agenda group: mygroup
Then, in the test code, as you can see I'm using the agenda-group I wanted by locating it on the agenda and setting it in-focus: https://github.com/tarilabs/demo20230212-so75416633/blob/main/src/test/java/org/drools/demo/RuleTest.java#L58-L69
session.getAgenda().getAgendaGroup("mygroup").setFocus();
session.fireAllRules();
So to me I cannot reproduce any error in using agenda-groups using latest Drools available at the time of writing.
You mention you are using Spreadsheet (.xlsx) for defining the rules, and the agenda group "1" is very suspicious it might be interpreted wrongly as number Vs string.
I hope with my very first snippet above, you are able to re-instate the inspection of all the agenda-groups defined in all rules in all packages, so to verify your agenda-group "1" is really present.
If not, suggesting you try by writing in Excel as "aaa1" instead of the simple digit for one, so to make sure it is correctly saved in the Excel as a string.
