Guest OS file restore process not working with v8 API?

[Mardock]

Hi,

I must start the guest OS file restore process of the VM from the specified restore point.

If I make a POST to URL /catalog/vms/{vmname}/vmRestorePoints/{ID}?action=browse the server response with the following error:

Code: Select all

<?xml version="1.0" encoding="utf-8"?>

I have update veeam API from v7 to v8.0.0.917. With v7 the POST work well but now with v8.0.0.917 it doesn't work...

Any idea?

Thanks,

I'm wondering whether you're creating session, using new version of session manager (http://localhost:9399/api/sessionMngr/?v=v1_1) and not the obsolete one. Thanks.

Hi,
now I'm using new version of session manager (http://localhost:9399/api/sessionMngr/?v=v1_1) but the server returns the same error...

Thank you,
Mardock.

Sorry, I make a clarification ..

I noticed that if I using HTTP (http://{veeamserver}:9399/api/sessionMngr/?v=v1_1) version of session manager then the POST work great.

The POST return the error only if I using HTTPS (https://{veeamserver}:9398/api/sessionMngr/?v=v1_1) version of session manager.

If I use the HTTPS session manager, all other restufull calls works fine.

Only the POST to URL /catalog/vms/{vmname}/vmRestorePoints/{ID}?action=browse produce the following error:

Have you opened a case? It looks like a bug from the first sight.
