Cannot access a disposed object #8462

CNS created

There is a problem when we are running different transactions and jumping from one appservice to the other but some how following error arises with in the transactions: : 'Cannot access a disposed object. A common cause of this error is disposing a context that was resolved from dependency injection and then later trying to use the same context instance elsewhere in your application. This may occur if you are calling Dispose() on the context, or wrapping the context in a using statement. If you are using dependency injection, you should let the dependency injection container take care of disposing context instances. Object name: 'ERPDbContext'.' Please explain

    Don't use void as the return type of an asynchronous method.

    private async void ProcessReceiptTransfer(VoucherPostingDto input) should be private async Task ProcessReceiptTransfer(VoucherPostingDto input)

    Please share your abp version and complete exception information (including other logs before and after the error.)

    hi @CNS

    Can you use Zero's demo project to create a simple project that reproduces the problem? Use the simplest code to reproduce the problem.

    Please share the project with me: liming.ma@volosoft.com

    private async void ProcessReceiptTransfer(VoucherPostingDto input) should be private async Task ProcessReceiptTransfer(VoucherPostingDto input)

    1. Have you made the change above?
    2. Can you share code for the caller of ProcessReceiptTransfer method?
