[Share conversation] Infinite loader is shown on opening share conversation link

[irinakartun]

EPAM AI DIAL chat version

0.13.0-rc

What happened?

Setup:

• conversation created several days ago exists in the system

Steps:
1 Select 'Share' option in the conversation dropdown menu
2 Copy share link
3 Open copied link by another user

Expected result: conversation with the history is opened
Actual result: conversation is visible on side panel; infinite loader is shown istead of chat history

The issue is reproduced sometimes. Possible conditions: share past conversation; conversation model is Rag

The issue is also reproduced for conversations with links and shared folder with conversations/prompts. Http 500 error is displayed in the console on opening DIAL home page:

The issue is possibly related with error response from recursive api listing:

Confidential information

• I confirm that do not share any confidential information

Issue also reproducible for folders with chats with attached/ produced files

Verified the fix on the staging env. using chats with link, images, pdf, just text created a month ago (or yesterday) and folders. Now no infinite loader appears.
Reported #2652 as in most cases single shared char is not focused.
