System.UnauthorizedAccessException: Access to the path 'C:\Windows\TEMP\ContinueRunningWorkflows5KC7QDLK4FML23TKRG7J52LIOPKUVFGU.lock' is denied.

By default, Elsa uses the DistributedLock package to acquire distributed locks. It is configured to use a temp file by default, which apparently is failing due to an authorization exception.

Unless this is a transient issue, you’ll have to give your app permissions to access the temp directory, or configure the distributed lock to use a different directory. Alternatively, you could configure it to use SQL Server, Redis, or any other provider it supports. This is especially recommended to do when hosting in a multi node cluster (not sure of this is the case for you).

It was working properly without any issue and yes, we use it inside multi VMs but this issue is raised suddenly without any change in our implementation.

In that case, I would encourage you to use a real shared resource such as Redis or SQL Server to acquire a distributed lock.

Not only will that prevent potential concurrency issues when two or more nodes attempt to run the same workflow instance, it will also work around this file access issue - which is beyond my control, and probably even beyond the control of the DistributedLock project.

MusabBasheer commented 1 year ago

Thank you for your support from where I can configure shared resource to be using SQL Server.

sfmskywalker commented 1 year ago

Here's a small example off the top of my head:

services.AddElsa(elsa =>
{
   elsa.ConfigureDistributedLockProvider(options => options.UseSqlServerLockProvider(dbConnectionString));
}

Make sure to reference the Elsa.DistributedLocking.SqlServer package, which provides the UseSqlServerLockProvider extension method.
