Error: module 'anyio' has no attribute 'Lock'

Raised in behalf of user as he is getting this error though using the .NET library and so far he is having no problems. He has already installed version eikon-1.1.14.

Will share link to user for him to provide additional information.


Please see details below.

Hi @nelbert.guantero

Can you ask the user to check the version of the Anyio library using 'pip list' command? I'm using Anyio v3.2.1 with Eikon v1.1.14 and I couldn't reproduce the issue you found, even using the same app key provided.

If the user is using another version of Anyio, please ask them to upgrade the library. But if they're using the same version, there could be any other issue and I'll try to find the cause and how to fix it.

Hi @raksina.samasiri, based on piplis previously sent by user, he has anyio version 3.3.4.

hi @nelbert.guantero ,

Could you please ask the client to downgrade anyio to version 3.2.1 and try running the code again? it could be that his current version of anyio module does not match the interface expectation by eikon library 1.1.14.
