Can anyone please provide any help?

Can anyone direct me to which json file this error is referring to?

Ok I was able to solve this issue by changing the white-lable.json file to default config. However, I still do not understand why the following json file was giving error. Can anyone shed some light?

{ “homePage”: { “header_text”: “WELCOME TO
MECA VIRTUAL CLINIC”, “logo”: “/bahmni_config/openmrs/apps/registration/registrationCardLayout/images/meca-logo.png”, “title_text”: " ", “showTitleText”: false }, “loginPage”: { “header_text”: “MECA VIRTUAL CLINIC”, “logo”: “/bahmni_config/openmrs/apps/registration/registrationCardLayout/images/meca-logo.png”, “showHeaderText”: false, “showTitleText”: false }, “helpLink”: { “url”: “https://bahmni.atlassian.net/wiki/spaces/BAH/overview” } }
