Odoo: Error viewing PDF stored on external server (Alfresco) from Chatter

Question

I am working with Odoo and I have a problem viewing PDFs in Chatter after moving the files to an external server (Alfresco).

What I do:

1. Users attach PDF files in Odoo, which can be viewed correctly from Chatter.
2. To optimize storage, I move these PDFs to an Alfresco server.
3. Then, in the Odoo database, I modify the attachment record:

• I change the type field from “binary” to “url”.
• I store the URL of the file in the url field.
• I delete the values of store_fname and checksum in ir.attachment.

When I try to view the file again in Odoo, I get this error:

An error occurred while loading the PDF.
PDF.js v2.16.105 (build: 172ccdbe5)
Message: file origin does not match viewer's

However, I can download it without problems from Odoo. How can I make Odoo allow to display the PDF correctly from Chatter?

Answer 1

I don't know odoo and chatter, but I think you have to take care of CORS Configuration in Alfresco. That would explain the error message complaining about origin.
