...ANSWER
Answered 2021-Jun-14 at 07:11The way you use it caught my attention. Out of general use. Generally, api operations are done with packages such as saga or thunk. Action is only used as a hyperlink. I suggest you review the article below. I think this build will solve your problem.

QUESTION
I am learning Redux Thunk now. I tried to use createAsyncThunk
