How to create two multi value fields to produce a json object of name value pairs?

I have this Query that produces two multi value fields, keys and values.  What i need to do is pair each entry in the keys multivalue field with it's matching value in the values multivalue field to create a json object that looks like this.

{ key1:val1, key2:val2, key3:val3 }

index=test5 earliest=@s-24h
apicall IN (aws_es_listDomainNames aws_es_listTags) NOT err
| eval resourceid=coalesce(resourceid, DomainName)
| eval uid=resourceid+accountid+region
| rename "TagList{}.Key" AS keys
| rename "TagList{}.Value" AS values
| eval tags=mvzip('keys','values'," = ") | nomv tags.    //  this matches up the key and value pairs but isn't useful with json_object.
 
I've tried using json_object but json_object only accepts arguments and not a string of key value pairs.  Is there a way to produce a json object from the two multivalue fields above?
 
Thanks.

Hi, I think something like this will work

| makeresults
| eval json="{ \"stuff\":[{\"name\": \"name0\", \"value\": \"value0\"},{\"name\": \"name1\", \"value\": \"value1\"}] }"
| spath input=json
| rename "stuff{}.name" as names,
"stuff{}.value" as values,
| eval range=mvrange(0,mvcount(names)),
stuff=mvmap(range,"\"".mvindex(names,range)."\":\"".mvindex(values,range)."\"")
| nomv stuff
| eval stuff="{".replace(stuff,"\n",",")."}"
| table json stuff

My bad.  This is a bit cleaner.  Clearly I'm up too late and forgot about mvjoin

| makeresults
| eval json="{ \"stuff\":[{\"name\": \"name0\", \"value\": \"value0\"},{\"name\": \"name1\", \"value\": \"value1\"}] }"
| spath input=json
| rename "stuff{}.name" as names,
"stuff{}.value" as values,
| eval range=mvrange(0,mvcount(names)),
stuff=mvmap(range,"\"".mvindex(names,range)."\":\"".mvindex(values,range)."\""),
stuff=mvjoin(stuff,",")
| eval stuff="{".stuff."}"
| table json stuff
