Everything was going well and the many errors came up. 

All ending in ....as defined in 'web.assetts_backend'

I was working on a custom module, everything was going well then it all just stopped???

Any ideas?

I can't copy all the lines except by adding a linked screensho with as many errors as possible

Thanks in advance
