Genesis error when trying to edit new blocks: Unable to find 'WSMU'

hi folks,

When trying to edit some new blocks I've added in Genesis, I'm getting the error "Unable to find the Workspace Assembly Service Factory class for name 'WSMU' in Workspace 'Genesis' and Maintenance Unit 'X'"

any idea why? I'm getting the error when i try to load a 'cube view basic' or 'embedded label' so far, in a card in a row in an advanced formatting block

Great. I suspect you might have hit a versioning conflict e.g injecting a 2.0 block into the 1.0 Genesis frame

Hi keski​ 

I just ran through the same steps, without any issues on Genesis 2.0 using both 2.0 Blocks mentioned (I just downloaded latest from Solution Exchange) e.g.

  1. Create a Card
  2. Inject a Block
  3. Edit Block
  4. Preview Results

 

To clarify are these the same steps you mean by Edit Block (see image below)?

Also, please can you advise which (a) OneStream Platform and (b) Genesis version(s) are you using?

Sam
