Perfect! Thank you a lot for adding this!

Had one comment

I also started wondering if we don't want to have it on the RPC plugin settings instead — e.g. someone may not use RPC at all, and then it's not clear what onError setting refers to. What do you think?

[Zeko369]

Hmm but we have 2 onErrors, one for BlitzServer and one for RPCHandler?

The only thing actually missing is that BlitzServer one is only used in API routes not in SSR/SSG and that might me useful?

Update on the last comment, I added error handling into GSSP / GSP / API functions

Ok, after further thought, I think it's good. Thanks again for working on that — it's super helpful !!
