在本地，代码工作正常。我能够使用kafka消息，但在开发人员中，出现错误提示
df <- structure(list(gender = structure(c(1L, 2L, 1L, 1L, 2L, 1L, 2L, 2L, 1L), .Label = c("Man", "Woman"), class = "factor"), shoe = c(43L,36L, 43L, 36L, 43L, 44L, 38L, 37L, 41L), height = c(176L, 166L,182L, 151L, 183L, 184L, 164L, 160L, 175L), colour = structure(c(3L,2L, 4L, 2L, 1L, 1L, 2L, 2L, 2L), .Label = c("Blue", "Brown", "Green", "Other"), class = "factor")), class = "data.frame", row.names = c(NA,-9L))
将Azure开发者用作开发者主机
代码：
