AI suggestion doesn't work

I’ve configured openrouter integration and validated that credentials work. Created default prompts for all three contexts (pre-translate, qa, editor). But when I actually open an interactive translation UI, it tries to fetch AI suggestion and fails with “unable to load messages” error:

I do not see any related activity on openrouter activity page. What might be the problem and how can I get more diagnostic error details than that?

Hi there,

We understand you’re encountering an “unable to load messages” error when trying to fetch AI suggestions in the interactive translation UI. To assist you further, could you please check your AI balance and ensure that the tokens limit has not been exceeded? Additionally, you can review the AI logs for more detailed error information under the Tools tab → Service logs.

Looking forward to your kind reply,

@Tania I do have sufficient token balance ($10, can’t post screenshot because of 1 media per post limit)

The problem is not with balance. Crowdin fails to even place a request to openrouter. Looking at AI assistant context, it fails to load any strings, which matches the error that I posted above:

Hi @extesy ,

We would need to investigate the case on our side. Could you please send us the link to your project (you can send it to support@crowdin.com)?

Thank you, I sent a link to my project to your support email. Hopefully, you’ll be able to investigate a problem further.
