What problem caused this error

Are you trying to use the CLIP output from the Load Checkpoint like this:

No, it doesn't work. SD3 has its dedicated CLIP Loader called TripleCLIPLoader. You do this instead:

If you want to use my custom version of SD3 nodes, which I think is more understandable, at least I removed the unused CLIP output which caused your confusion, here is the link:
