I was trying to encode the string values of the feature 'ProductCategory' into integer values but I got this error. Kindly help.
And I would also like to ask if label-encoding this feature would not force my model to misrepresent the integer values as 0<1<2. Thanks.
LabelEncoding, if not processed again before passing into the model, will impose an order on the categories (namely the 0<1<3) that you mentioned. Here, since it does not seem like you have a lot of categories, one-hot encoding is the easiest to implement and also more effective (the categorical values are nominal rather than ordinal here).
These two articles are a decent starting point for categorical encoding in Python: https://pbpython.com/categorical-encoding.html

As for the TypeError, can you double check what variable type train_df is?
