Your integration update introduced a new variable (companyId), and you use it in your updated SCIM server base URL. The base URL changed from https://fruits.example.com/scim2/myapp/ to https://fruits.example.com/scim2/myapp?connection={app.companyId}. In this case, ensure that the dynamic base URL is also valid for existing instances where the companyId value isn't set.
To handle empty companyId values, you can define the base URL as:
'https://fruits.example.com/scim2/myapp' + (String.len(app.companyId) == 0 ? '/' : '?connection=' + app.companyId)This expression handles scenarios where companyId is populated or empty. See Dynamic properties with Okta Expression Language.
