Nonetype-Object is not iterable

Post by TeAge1 »

Hey!
Does anyone here also have that problem? The search-function didn't find anything, but am i really the only one? What does it mean?
When this message comes up, it doesn't work anymore at all and i have to reboot everything.

Have a nice day!
Tobi

Spreads is relatively fragile and the error-reporting process can be a bit frustrating. Basically this means that something has gone wrong (camera crashed or failed) and some later piece of code was called with an empty object instead of the photo data it was expecting. If you click shutdown and reboot, then Spreads should be happy to continue. Sometimes you can still soldier forward by clicking the end capture button, turning on the camera again after a crash, then clicking capture again on the workflow you want.
