The expression "do shopping" is not grammatically incorrect without the definite article "the" or possessive pronoun "one's." However, it is more common and idiomatic to use the definite article "the" or possessive pronoun "one's" with the phrase "do shopping" to specify the specific shopping activity being referred to. For example, "I like to do the shopping on Sundays" or "I like to do my shopping at the local supermarket."
