I just started researching the development of WeChat public accounts and customized the menu. It always prompts 44002. Is this error, or is it the error 40001? Is it a test account permission issue? Shouldn’t the test account have all the permissions? I repeatedly checked the correctness of the sent content and appsecret, and they were all correct, but it was unsuccessful and I don’t know why. Please give me some guidance! ! !
