@raff I uploaded only openconceptlab 1.2.2 module to openmrs (without owa module) and I still see error when I go to status page or configuration page from openmrs legacy UI. Now, I loaded owa module and copied the openconceptlab.zip (from master branch) to /opt/openmrs/owa, unzipped it just like suggested by @binduak. Now when I open the openconceptlab from Manage Apps in openmrs UI or the status page, I only see a green bar.

The issue is with bahmni version 0.90. With Bahmni-0.89, openconceptlab-1.2.2 and owa-1.8.1 everything is working fine 
Looks like it could be due to openmrs upgrade because, it’s working fine with version 0.89 with bahmniapps from version 0.90
Hi Pramida, it worked for me in 0.90 with this new version, after shift refreshing.
