问题 Here's my code: async [types.GET_DATA]({commit, state}, data) { try { const res = await axios.post('/login', { email: data.email, password: data.password, }); console.log(res) } catch(e) { if(e.response) { console.log(e.response) } } } So, I return 400 Bad Request whenever user sends empty fields.

问题 In Visual Basic, there is an inherited base object that is effective for error debugging purposes. Is there an equivalent for the "Err" object in Python?
