When I try to save a component with an ECL image linked as component link I'm having an error related to "The given key is not present in Dictionary". I changed the log of ExternalContentLibrary to Debug and I can see:

It seems a problem with the socket timeout but I don't know which service is to increase the time. Also, all the lines in stack trace are related to SDL code or .net code. I don't see any stack trace of my provider. Any idea? Thank you!

I found the solution to my problem.

Basically, I was generating a different EclUri when I was creating a multimediaItem in GetFolderContent and when I create it in GetItem.

The subtype that I was assigning was different.

As said Hiren, The key was:

The given key was not present in the dictionary.

It seems CMS code verify the EclUri. It has to be consistent in all the process. Well done!

Looking at the entire error message socket timeout error is misleading.

The main error is:

The given key was not present in the dictionary.

That means the image that you have referenced in the component has been deleted from image library so due to stub component you are able to refer to it however stub component is not able to locate the image on image library (digital asset management system).

Try to change image to some other existing image on external content library and it should work fine.

Update

In that case there are issues with ECL where data is properly indexed so data that is required to save the component like ECL id is not received in time due to which you are seeing timeout. Recommendation: 1. Check the ECL service is working properly 2. Index the ECL database.

    But It's when I try to save it. I navigate in my ECL Folder provider, I select the image and then I click on Save button. Then, the image exists in the image library. I suppose when I click on save the system calls GetItem / GetItems from my mountPoint class. I surrounded all the methods of my MountPoint in a Try/catch but I cannot capture any error. This is the reason that I think that the problem is in other place.
