What do I do if a field isn't showing up in VB Studio and I'm getting an error on loading the page?

Ask the Oracle Cloud Applications administrator to enable Cross-Origin Resource Sharing (CORS) by adding the Oracle Visual Builder Studio's root URL to the Oracle Cloud Application's ORA_CORS_ORIGINS profile option. This profile option specifies which domains can talk to each other.

Production to Test (P2T) and other operations that replace the database might cause the profile option value to change. If you perform any operation that replaces the database, then you must reset the ORA_CORS_ORIGINS profile option using the Manage Administrator Profile Values task in Setup and Maintenance.

In the Site level, Profile Value field, enter 'self' (including the single quotes), followed by VB Studio's root URL. For example: 'self' https://abcd-test-DEVCSAPP-07012210-2070-abcd.developer.ocp.oraclecloud.com.

Note:

Don't include port numbers, wild cards, or extraneous characters after the root. For example, if the VB Studio’s full URL is https://abcd-test-DEVCSAPP-07012210-2070-abcd.developer.ocp.oraclecloud.com:443/abcd-test-devcsapp-07012210-2070-abcd, the root is simply https://abcd-test-DEVCSAPP-07012210-2070-abcd.developer.ocp.oraclecloud.com.
