Can't really tell without some source, but, judging by the error it seems like you might be using Suspense which doesn't yet work with gatsby's SSR renderer: https://www.gatsbyjs.org/docs/using-client-side-only-packages/#workaround-4-use-reactlazy-and-suspense-on-client-side-only
Replacing with loadable would be the way to go.
Hi @abdokouta !
Sorry to hear you're running into an issue. To help us best begin debugging the underlying cause, it is incredibly helpful if you're able to create a minimal reproduction. This is a simplified example of the issue that makes it clear and obvious what the issue is and how we can begin to debug it.
If you're up for it, we'd very much appreciate if you could provide a minimal reproduction and we'll be able to take another look.
Thanks for using Gatsby! 馃挏
@arthurjdam thank you for the help i have been into this for 5 days in a row. i will let you know the result.
@arthurjdam after removing Lazyloading i'm getting this error any recommendations please?

Not sure without a deeper look into the relevant code, but I assume replacing your suspended component with one through loadable will sort it out: https://github.com/gregberge/loadable-components#example
@arthurjdam i will check and let u know, i have one more question do u have any direct contact line i would like to ask about some stuff related to our project and gatsbyjs. Thank you

Hey folks,
I was getting the same issue then I removed the code of Suspense and Lazy load from my file. It worked!
I hope it may work for you as well until they add the support for these.
Happy Coding!
@vladar I have been trying to deploy my gatbsy app on Netlify but I keep getting this error, not sure why is this happening. Here is how my gastby-config.js file looks like

}

I'm going to close this thread, please re-open new issues if you have any problems.
Please checkout https://www.gatsbyjs.org/docs/debugging-html-builds/ for more information.
I have a same issue, I search the codes if I have lazy or Suspense, but I didn't find any code like that. How do I resolve this issue?

It shows in the error: ReactDOMServer does not yet support Suspense
To fix, replace your use of Suspense with loadable
