EEG lab topoplot function

I just have a problem, I am running the matlab code on matlab 2017, however, i have a problem calling topoplot function from eeg lab directory. Everytime I run the code, I got this error "Error using matlab.graphics.chart.primitive.Contour/set There is no cdata property on the Contour class. Error in topoplot (line 145) set(h, 'cdata', [], 'edgecolor', 'k')"

topoplot is this inbuilt function? Or Can you share more?

Which version of EEGLAB are you running? Can you show us a minimal version of the code used to call this function? Remove everything unnecessary to reproduce the error. Also it wouldn't hurt if you could upload your data as well.

Potential problems are: incompatible versions of the toolbox, you've overloaded a function with a variable name, feeding the wrong data type into the function. But we cannot tell without more information.

您好，请问呢我运行topoplot_connect时一直报错函数或变量 'topoplot_connect' 无法识别。但路径里已经添加了eeglab包含的所有子文件夹，请问这如何解决呢？麻烦您了！
