I just had this problem trying to deploy an ova. In Chrome it failed with the same error. In Firefox, it succeeded with no errors.
vCenter : 6.5 (Build 751524)
ESXi: 6.5 (Build 7388607)
for real with firefox?
in my case I've been trying to export some VMs as OVF and won't work all
it's stuck a 33%, last time I tried and I leave the task running, 16 hours later still at 33% no matter chrome, firefox, flash o html 5
I have this OVF issue with my vCenter.
I run vCenter 6.5.0 build 8024368 that seems to me above the VMware vCenter Server 6.5 Update 1d (build 7312210), so it should contains the resolution for the issue.
But maybe I'm wrong.
So please advise me if my analysis is correct.
Thanks in advance for the help.
I had the same issue this week. It was the first time attempting it so I can't say it ever worked before. However, the virtual appliance installed was a fresh install and not an upgrade.
I upgraded the virtual appliance two from version 22.214.171.12400 to version 126.96.36.19900. The issue did not go away. It actually seemed to get a little worse. It went from starting the ova export and getting stuck at 25% to not starting the download at all. It led me to believe it might be the browser. I added an exclusion for Java in chrome for the virtual appliance URL. Tried it again and to my surprise, it worked. The actual .ova file was the first thing to download. Prior to that, it was a tiny vmdk. This time I ended up with four files. and ovf a vmdk for each disk and a .mf file.
Now I guess I need to import it to test.

My problem to deploy an OVF was due to the size of the OVF (more then 10 Go).
Using IE 11 to connect to the vCenter and then start Deploy the OVF but if failed with the "...invalid parameter" error.
I have found some articles related to a limitation of file size that IE can handle for such action.
With Firefox, I have no more the issue.
I hope this help.
Thank this was a life saver!
i had the same problem,and have solved it by using another browser. you can try
this is a long running thread that will probably attract attention of many people struggling with OVF/OVA import/export with vSphere.
As a workaround I want to point anyone to a free Java based GUI tool that will get every job related to OVF/OVA done for you quickly and without the need to struggle with the oddities of the vSphere Web Client:
It's the VMDeployer tool created by stevejin
