Thanks for your bug report. When I test your script, I see a /sockwrite error.

Do you mean that you are seeing a /sockwrite error as well? And that you think you should see a $bfind() error?

If that's the case, why do you think you should see a $bfind() error? Did you add debug /echos to track what is happening?

Can you create a simple, one line script using $bfind() that reproduces your issue?
