Just did my first successful build with the converted version of my fb6 project, but the server seems to have had some trouble with the logging server's response as it ended (as far as I can tell, my script ran to completion):
FinalBuilder Server Error
FBCMD exception: The response sent back from the logging server cannot be deserialized into type 'BuildVariableValueDef[]'. Log Response:
QzpcV0lORE9XU1xzeXN0ZW0zMg==
QzpcV0lORE9XU1xzeXN0ZW0zMlxjbWQuZXhl
... [it continues for a quite a while in this manner].
I'm unable to see the log for the run, which I suppose doesn't surprise me, given the nature of the problem.

Hi Liam
Are you able to send us the full output from the log. It is base64 encoded xml… if we have that we can see what t he xml serializer is barfing on.

Unfortunately I don't think I can do that at the moment. The log contains some company-sensitive data. I'll ask the powers that be what is possible.
Interestingly, I haven't had the error since that time. My log is behaving fine, regardless of whether my builds succeed or fail. But I can't get back to the log for that run - the web server gives me an error when I try.

Ok, if it happens again let us know, you can send any info to “support at finalbuilder dot com” and it will be treated in confidence, we deal with customers project and log files all the time.
