Hey hey. I`m try capmonster instead rucaptcha and get this message

[Executing block Solve Image Captcha] TaskSolutionException: Buffer_cannot_be_null.

If you’re on capmonster cloud, use the CustomTwoCaptcha option and manually put the settings.

Not capmonster cloud, simple capmonster and I`m using it for simple ocr
As I can make my own ocr plugins

Then make sure the image you pass is an actual image, it seems to be saying that it’s an empty buffer.
