Cannot access a disposed object #8462 | Support Center

CNS created 4 years ago

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

1 Step :

    {
        var receiptHeader = _porecHeaderRepository.GetAll().Where(o => o.TenantId == AbpSession.TenantId

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.)

System.ObjectDisposedException: 'Cannot access a disposed object.

Your app has entered a break state, but there is no code to show because all threads were executing external code (typically system or framework code).

this error arises normally when 2 time loop executed

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: [email protected]

all other services are working fine but on this service we are facing problem. I already shared whole problematic code with you.

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

Have you made the change above?

Can you share code for the caller of ProcessReceiptTransfer method?
