TypeError when viewing some event transactions

[Spikatrix]

Self-Hosted Version

25.7.0

CPU Architecture

x86_64

Docker Version

28.3.3

Docker Compose Version

2.39.1

Machine Specification

• [x] My system meets the minimum system requirements of Sentry

Steps to Reproduce

I upgraded my self-hosted instance from 24.9.0 to 25.5.1, and then to 25.7.0.

Now, I'm unable to view some of the transactions from the discover page, both newly generated ones after the upgrade and some older ones. It however works for some transactions in there.

Expected Result

I'm able to view all transactions successfully.

Actual Result

Clicking on some transactions takes me to the view traces page (example). It shows a loader for a few seconds and then shows "Woof. We failed to load your trace. If you need to yell at someone, send feedback".

Do you have all the feature flags defined below on your sentry/sentry.conf.py file?

https://github.com/getsentry/self-hosted/blob/3f48e35813edf22ae8dee170ea6645900440b117/sentry/sentry.conf.example.py#L282-L347

[Spikatrix]

@aldy505 Yes, I pretty much use the defaults

[aldy505]

Hi, can you try upgrading to 25.8.0?

[Spikatrix]

I'll try it out soon. I'll also try switching back to rust-consumer as mentioned here and see if that helps

[Spikatrix]

I switched back to rust-consumers and upgraded to 25.8.0 but the issue still persists unfortunately.

[RahulLanjewar93]

I am facing two issues

1. In issues tabs, the transactions and spans are not visible. On checking the network request, it seems subscriptions api is faling. https://github.com/getsentry/sentry/issues/96077
2. In transaction summary view, some api calls for project-transaction-thershold is returning 404 http error code

i use 25.9.0 ,I'm having the same issue.
