Demo summary

The creator shows how to import a local JSON workflow into Running Hub and resolve 'red node' errors by re-mapping missing T5, Clip, and VAE models to the platform's available versions.

Step-by-step

  1. Click Import and select your local JSON workflow file
  2. Click on the workflow name in the list to open it
  3. Identify 'red nodes' indicating missing models or incompatible names
  4. Click the model selection dropdown on the Dual Clip Loader node
  5. Search for and select the T5 and Clip L models available on the platform
  6. Select the appropriate VAE model from the list
  7. Enter your prompt and settings
  8. Click Run to execute the workflow and verify the fixes

Options

  • Rename, copy, or delete workflows from the list
  • Filter models by typing names like 'T5' or 'CL' in the search bar
  • Hide the task list while the generation is running

Watch out for

  • Workflow titles must be under 50 characters or you will receive an error message
  • Workflows must be successfully run once before they can be made public

Tips

  • Select the fp16 version of the T5 model for higher quality generations
  • If a specific model doesn't work, try selecting others in the list until you find a compatible version

Highlights

“if a model doesn't work you can select another one until you find one that works now when I run it again everything works fine and there are no errors anymore”
