Extract js object with nested js object with grok processor

I have this sample log below that I want to extract the JS object in here to stripeError. I'm not able to succesfully and cleanly extract it all.

First try

I deally I was hoping to do a rule like this:

extract_stripe_error_rule [^{]*?%{data:stripeError:json}.*

And it would see it as json, but because they keys don't have quotes around it, and single quotes are used, this is a JS object so that doesn't work.

Second try

extract_stripe_error_rule [^{]*?%{regex("[^}]*"):stripeError:keyvalue(": ")}.*

But this doesn't get the nested js object. And then some keys are turned into arrays.

Third try

To handle nested js objects, I see the first one is raw and then in here is raw.headers.

extract_standard_error_from_stripe_error_rule Stripe[a-zA-Z]+Error: %{regex("[^\\n]*"):error.message}\s*%{regex("[^{]*"):error.stack}%{regex(".*?"):stripeError:keyvalue(": ")}raw: \{%{regex(".*?"):stripeError.raw:keyvalue(": ")}headers: \{%{regex(".*?"):sripeError.raw.headers:keyvalue(": ")}\},\n%{regex(".*?"):stripeError.raw:keyvalue(": ")}\},\n%{regex(".*?"):stripeError:keyvalue(": ")}headers: \{%{regex(".*?"):stripeError.headers:keyvalue(": ")}\},\n%{regex(".*?"):stripeError:keyvalue(": ")}$

This now does extract things succesfully, however it creates arrays, as I had to repeat the parts around the nested objects. And also due to repition, some of the stuff is excluded, as you see myCustomKeyToTest is not included.
