I'm working on an ECL integration for Web 8.5 right now. My plan is to resolve the ECL components with my own TBB. However, I cannot even publish a page using the default DXA TBB.

"Generate Dynamic Page (DXA)" throws an error when trying to resolve my ECL component.

ComponentBuilder: start BuildComponent with component ecl:0-cel-226-cea-file (tcm:1262-422810) and link level 49
EclProcessor: Retrieving ECL item for ECL Stub Component: tcm:1262-422810
ECL item 'ecl:1262-cel-226-cea-file' not found (TCM URI: 'tcm:1262-422810')
   at DD4T.Templates.Base.Utils.EclProcessor.GetEclItem(String eclStubComponentId, IContentLibraryContext& eclContext)

Am I missing something here?

Page Template contains:

 - Generate Dynamic Page (DXA)
 - Resolve Rich Text

Component Template for this component contains:

- Resolve ECL items V2
- Generate Dynamic Component (DXA)
- Publish binaries for component
- Resolve Rich Text

I can open the TCM-ID and the ECL-ID in the CMS, they both exist.


Kind regards


  • Welcome to Tridion Stack Exchange, looks like this item tcm:1262-422810 does not exist in cms, double check that ECL item in that component linked it exists or not try to open that item to see? please edit your question to update what are the TBBs added in your component template and page template, is that ECL folder displays correctly on your pages level publication is it working as expected?

  • Thanks for your answer, i can open the TCM-ID /WebUI/item.aspx?tcm=16#id=tcm:1262-422810 and the ECL-ID /WebUI/item.aspx?ecl=file#id=ecl:1262-cel-226-cea-file in Tridion. They both exists and look fine. The ECL folder also looks fine in the publication.

    Link Level 49 ?! Is that really needed? Commented May 30, 2018 at 20:21

It looks like you have not added Resolve ECL items V2 to your Component Template TBB.

In the template builder folder, you can see SDL External Content Library and named Resolve ECL items V2. Add this to your Component Template and it will deal with the ECL item.

I hope it helps.

  • ECL was installed with Web 8.5 but there is no "SDL External Content Library" folder in the template builder.

    If all is well, the “Resolve ECL items V2” TBB should not be required for DXA; you can see in the error message that DD4T templates will resolve links to ECL Stub Components anyways. I don’t know why you got that error, though. Can you check if it re-occurs if you remove the “Resolve ECL items” TBB again? Commented May 30, 2018 at 20:20

    Also check out Jonathan’s Answer; it can explain why things all of the sudden start working (and later magically break again). Commented May 30, 2018 at 20:25

If your Publisher is outscaled onto a separate Windows server, then you'll need to make sure that the ECL mountpoints are configured correctly on that server too.

I've been caught-out by that before!

P.S. You'll need to restart the SDL Publisher Windows Service after making the change.
