Hello 

You need to delete config

ah crap, i hit the wrong link instead of replying the post, i hit the Report Reply.

I already did deleted all config and data from convoy, then got that error.

Try deleting it again. I'm pretty sure the problem is in the config

Changed Status from Pending to Work in Progress

Changed Status from Work in Progress to No Response

it seem to have worked, got no errors since, sorry for the no reply yet.
