'_io.StringIO' object has no attribute 'sync_write'

[cvar66]

Not sure what's happening, never had an issue until recently. When trying to use the Efficacy Loader I always get this error now.

let me review this and update. if you can share the exact dummy workflow where this happened it can be very useful

I just had the same problem, but I was able to use it normally this morning until I updated "comfyui-manager" to the latest version. I returned to normal use after trying to restore the previous version of comfyui-manager, hope my experience was helpful to you.

If it helps, I have this problem using "Efficient Loader". By deleting it, I no longer get the error.

I occurred the same issue, fixed after I updated ComfyUI-Manager. https://github.com/ltdrdata/ComfyUI-Manager/issues/841#issuecomment-2211757944
