Have you added any custom workflow model ? If so try removing that and see if the OOB workflow models comes up

[ramyan60274153]

Thanks for the reply...

We have many custom workflow model and workflow console shows empty list.

[img]wf-console.PNG[/img]

if I open the workflow model from etc/workflow/model getting the error (please see the attachment.)

all the workflows were working fine and those were listed even in the sidekick. our author instance was down and we had remove index.tar files and gave read and write access to data.tar files.

is that cause any issue. please suggest

[Lokesh_Shivalingaiah · Accepted solution]

yes !! that might have corrupted the tar files and may be the issue. If you want to really debug this issue, please raise the support ticket and they should help you in looking at it as it needs lot of time to figure out.

else, start a fresh instance and deploy all your code and packages and it should work fine again.
