In nuxt SSR app with just a single route I am getting `transaction.op` as `navigation`

Reproduction Example/SDK Setup

I have a very simple SSG(Static site generation) nuxt app with a single route marked by beforeStartSpan name:join-nuxt span.

Since it is only a single page there is no possibility of having navigation transactions. Not sure how sentry is tagging the transactions as navigation?

My guess is since this is a server side generated static page the whole transaction is coming up as a span & getting marked as navigation, because almost 50% of the traffic is being shown as navigation which is what corresponds to logged-out behaviour or completely static behaviour.

Steps to Reproduce

1. You should be in a VPN of Indonesia or India.
2. Go to Incognito in your browser.
3. Open https://wayground.com/join & if you are lucky the trace should show up since we do a 5% sampling.

Expected Result

Have zero navigation transactions, all the transactions should be tagged pageload only. Since the app only has a single page, which is statically generated at build time & can only have pageload.

Actual Result

Basically the span data should be looked into for a Static Side Generated or Server side Rendered route in Nuxt

Hello,

the reason for this, I believe, is that some redirect is happening. For example, there is this pageload:

https://quizizz.sentry.io/explore/discover/trace/59a8633514c14a409eb843fad4b6881a/?dataset=transactions&field=title&field=project&field=user.display&field=timestamp&name=All%20Errors&node=span-96af872eb9ff7f4e&query=&queryDataset=transaction-like&sort=-timestamp&source=discover&statsPeriod=14d&timestamp=1752129387&yAxis=count%28%29
Followed by this navigation: https://quizizz.sentry.io/explore/discover/trace/b492472fe52c4309b0b909cd789a56f4/?dataset=transactions&field=title&field=project&field=user.display&field=timestamp&name=All%20Errors&node=span-9d204bedb5790738&query=&queryDataset=transaction-like&sort=-timestamp&source=discover&statsPeriod=14d&timestamp=1752129387&yAxis=count%28%29

The pageload has a gc query param, which the navigation does not have. Possibly this URL change triggers a navigation.

But before we look more into this, can you update the SDK to the latest version? You are on 8.47.0, the latest version is 9.36.0, we have fixed a lot of issues in the Nuxt SDK in the meanwhile.

@chaitanyaQz Any updates from your side? I just tested this with a single-page Nuxt SSR application and only got a single pageload root span.

I'll close this now but if this continues to be an issue, we can re-open this at any time.
