can anyone advice? why i got this sudden error on page first load?

here is my main web part settings:-

now after some playing with the setting, i have noted if i remove the first 2 filters (highlighted in red) >> the web part will show data when the page first loads:-

but i still want to sort using those fields.. so can this give any additional info on the issue cause?
Thanks

If you can share the query JSON being made it's easier to see what the issue could be.

@wobba how i can get this JSON? can you advice?

[wobba]

F12, dev tools, look at the network requests for the search API call. @kasperbolarsen, maybe we should add docs on troubleshooting and looking at the JSON request/response?
