I have developed app in spfx which access sharepoint list and shows data with documentcards in a grid layout on a page.
When I deployed webpart on sharepoint side where this list is created app can not access this list
and console shows me
Failed to load resource: the server responded with a status of 403 ()
network tab of developer tools shows me
however I have full access to the site and also to list. List had permission inheritance enabled, but I disabled that and added all groups manually, during investigation.
What confuses me most is when I tried to deploy this app on other site, accessing still the same list app works and could retrieve data correctly.
