Judging by the fact that error takes place inside the component, I think it is this line, but the reasons are unclear for now

Thank you for providing the devtools screenshot, that does help with debugging.
What looks suspicious is the fact that the json response is 466 bytes (the last network request). That sounds a little bit small.
Could you take a look what is inside of it?

[soanni86]

yeah , its empty . 466 bytes thats only headers i guess

what backend is supposed to populate the data for these frontend requests ? dont see anything specifically wrong in backend services logs however

It seems that the proxy have rendered the json successfully and uploaded it into storage.
The proxy prerenders json to show by the UI.
It expects an absolute path to the storage.
Try checking that it is making a request to somewhere you expect.
Hover your mouse over the 0194dbbd-*.json line and check the domain. If there is no domain then check what is inside the rendered_profiles.url_prefix field in the proxy config
It is empty by default.
If it is empty you should swap it with a domain prefix or with an IP, something like http://[%IP_V6_IP]/ if you're using ip v6

great, thank now i see 500 while accessing directly the flamegraph https://perforator.dev-***.com/task/0194dce2-dace-7501-b3e2-fc5dbac9b3ea.json

in my logging system i see this error from postgres side

[gearoffortune]

I'm sorry, by "absolute path to storage" I meant, the path to this bucket, not "storage" microservice.

From what I understand the request is somehow reaching the postgres, and it really shouldn't. It takes the bucket link with the id and downloads it. So no postgres involved.
