I am using the latest opensource formsflow.ai v4.0.2. I brought the entire project to my personal laptop. I followed the Docker full installation guide. Docker is running fine. In http://localhost:3000, login as formsflow-designer and selected an existing form for associating workflow, If I select one of the forms it shows :unauthorized" as shown in the below screenshot.
This "unauthorised" error is due to wrongly configured environment variable for forms-flow designer role (DESIGNER_ROLE_ID). Please refer https://github.com/AOT-Technologies/forms-flow-ai/blob/master/forms-flow-forms/README.md#formsflow-forms-userrole-api for obtaining the required env for roles and use those in the environment variables mentioned in the table https://github.com/AOT-Technologies/forms-flow-ai/tree/master/deployment/docker#formsflowai-keycloak-variable-settings . And rebuild and deploy forms-flow-web. This should fix your issue.
