Web Channel works in Campaigns but not in Journey (SPA Integration)

Hi everyone,

The Web Channel is working when used in Campaigns — I see the message display correctly in my SPA.

But when I trigger the same Web Channel via a Journey, nothing appears in the app.
I configured a webevent and trigger that event in journey. The profiles are entering into journey but nothing appers in app.

I checked with debugger and dev tools , i observed the server is responding but not client.

FYI

What could be causing the message to work in Campaigns but not when coming from a Journey?

Any tips or things or I might have missed in the Journey setup?

Thanks
