This issue has been resolved in vRealize Automation 8.8.2 and later
Workaround:
To work around this issue you will need to update the vCF Cloud account via API call. To do this you need to capture the API request using a developer console in a browser like Chrome. To do this you open the Dev console and save the vCF Cloud Account. In the network output of the console you will find the PATCH request.
The following steps are based on using Postman and an authenticated user that has Cloud Assembly Admin Role assigned.
Back up your environment prior to making any changes.
