Angular web portal 9.0

Hello all,

We have recently upgraded our One Identity Manager instance from V8 to V9.0. We are now exploring the option of upgrading web portal to angular. After going through the documentation and the video series available we installed the API server and downloaded the project from GitHub.

When we're trying to access the angular web portal we are repeatedly getting error w.r.t API server as below.

failed to load resource : the server responded with a status of 500()

Also, in the documentation we found the text below.

##################################################################

Does it mean we need to install 9.1 API server. How it would be compatible with V9.0 database. Could anyone please provide more information regarding the above.

Kind Regards,

Sameer
