Error using the example workflow with ADD DETAILS enabled
Hello! I'm getting this error when i enable ADD DETAILS, at LTXV TILED SAMPLER:

Additional Context
(Please add any additional context or steps to reproduce the error here)```
Also, the group ADD DETAILS does not have VAE connection but a node GET_VAE, is it supposed to "auto attach" the VAE? The ADD DETAILS and LATENT UPSCALER are both missing VAE connection.
Had this error too, try reinstalling the ltxv video nodes, after some trial and error it randomly started working again
Yeah, it's not working for me either. An alternative is to hook the initial "Set_VAE" node to the circled connectors.
I was having this issue too. It looks like there was a recent change in the LTXV Tiled Sampler node that removed the optional_cond_image parameter. The workflow was still using this parameter which seemed to be causing the issue.
To solve it I updated to the nightly ComfyUI-LTXVideo custom nodes. Then I added a new LTXV Tiled Sampler node to this workflow, changed the parameters to match the old one, and reconnected everything to the newly added node. Once I did that the workflow ran successfully.
