Decomposing Erreygers CI Error: The X variable takes the value outside the specified limit (1 0)

[Chowdhury Rupok]

$X has list of categorical variables which has more than 2 categories.
When I run the code it says that "The variable (age) takes values outside of the specified limits". age has 5 categories here.
