Two consecutive OPs after pipe or two jq OPs in one run?

I have to extract data from a slightly mis-formatted JSON string, hence I first pass it through sed & awk. What I have is a command like: sed 's/},/},\n/g' test.json |awk '/"characater"/ { gsub("\"characater\"", "\"char" ++n "\"", $0) } 1'| jq -r '.frames.frame.lps.lp|.characters[]|[.code_ascii,.confidence]|@tsv' to extract data from a JSON string that can be seen here: {"response":{"container":{"id":"41d6efcb-24d6-490d-8880-762255519b5f","timestamp":"2018-Jul-11 19:51:06.461665"},"id":"00000002-0000-0000-0000-000000000015"},"frames":{"frame":{"id":"5583","timestamp":"2016-Nov-30 13:05:27","lps":{"lp":{"licenseplate":"15451BBL","text":"15451BBL","wtext":"15451BBL","confidence":"20","bkcolor":"16777215","color":"16777215","type":"0","ntip":"11","cct_country_short":"","cct_state_short":"","tips":{"tip":{"poly":{"p":{"x":"1094","y":"643"},"p":{"x":"1099","y":"643"},"p":{"x":"1099","y":"667"},"p":{"x":"1094","y":"667"}},"bkcolor":"16777215","color":"0","code":"49","code_ascii":"1","confidence":"97"},"tip":{"poly":{"p":{"x":"1103","y":"642"},"p":{"x":"1113","y":"642"},"p":{"x":"1112","y":"667"},"p":{"x":"1102","y":"667"}},"bkcolor":"16777215","color":"0","code":"53","code_ascii":"5","confidence":"89"},"tip":{"poly":{"p":{"x":"1112","y":"640"},"p":{"x":"1122","y":"640"},"p":{"x":"1122","y":"666"},"p":{"x":"1112","y":"666"}},"bkcolor":"16777215","color":"0","code":"52","code_ascii":"4","confidence":"97"},"tip":{"poly":{"p":{"x":"1123","y":"640"},"p":{"x":"1132","y":"640"},"p":{"x":"1131","y":"665"},"p":{"x":"1123","y":"665"}},"bkcolor":"16777215","color":"0","code":"53","code_ascii":"5","confidence":"97"},"tip":{"poly":{"p":{"x":"1134","y":"640"},"p":{"x":"1139","y":"640"},"p":{"x":"1139","y":"664"},"p":{"x":"1133","y":"664"}},"bkcolor":"16777215","color":"0","code":"49","code_ascii":"1","confidence":"77"},"tip":{"poly":{"p":{"x":"1154","y":"639"},"p":{"x":"1163","y":"639"},"p":{"x":"1163","y":"663"},"p":{"x":"1153","y":"663"}},"bkcolor":"16777215","color":"0","code":"66","code_ascii":"B","confidence":"97"},"tip":{"poly":{"p":{"x":"1164","y":"638"},"p":{"x":"1173","y":"638"},"p":{"x":"1173","y":"663"},"p":{"x":"1163","y":"663"}},"bkcolor":"16777215","color":"0","code":"66","code_ascii":"B","confidence":"94"},"tip":{"poly":{"p":{"x":"1191","y":"637"},"p":{"x":"1206","y":"636"},"p":{"x":"1205","y":"660"},"p":{"x":"1190","y":"661"}},"bkcolor":"16777215","color":"0","code":"76","code_ascii":"L","confidence":"34"},"tip":{"poly":{"p":{"x":"1103","y":"655"},"p":{"x":"1111","y":"655"},"p":{"x":"1111","y":"667"},"p":{"x":"1103","y":"667"}},"bkcolor":"16777215","color":"0","code":"74","code_ascii":"J","confidence":"57"},"tip":{"poly":{"p":{"x":"1103","y":"655"},"p":{"x":"1111","y":"655"},"p":{"x":"1111","y":"667"},"p":{"x":"1103","y":"667"}},"bkcolor":"16777215","color":"0","code":"74","code_ascii":"J","confidence":"57"},"tip":{"poly":{"p":{"x":"1176","y":"638"},"p":{"x":"1185","y":"637"},"p":{"x":"1184","y":"661"},"p":{"x":"1175","y":"662"}},"bkcolor":"16777215","color":"0","code":"52","code_ascii":"4","confidence":"7"}},"ncharacter":"8","characters":{"characater":{"poly":{"p":{"x":"1094","y":"643"},"p":{"x":"1099","y":"643"},"p":{"x":"1099","y":"667"},"p":{"x":"1094","y":"667"}},"bkcolor":"16777215","color":"0","code":"49","code_ascii":"1","confidence":"97"},"characater":{"poly":{"p":{"x":"1103","y":"642"},"p":{"x":"1113","y":"642"},"p":{"x":"1112","y":"667"},"p":{"x":"1102","y":"667"}},"bkcolor":"16777215","color":"0","code":"53","code_ascii":"5","confidence":"89"},"characater":{"poly":{"p":{"x":"1112","y":"640"},"p":{"x":"1122","y":"640"},"p":{"x":"1122","y":"666"},"p":{"x":"1112","y":"666"}},"bkcolor":"16777215","color":"0","code":"52","code_ascii":"4","confidence":"97"},"characater":{"poly":{"p":{"x":"1123","y":"640"},"p":{"x":"1132","y":"640"},"p":{"x":"1131","y":"665"},"p":{"x":"1123","y":"665"}},"bkcolor":"16777215","color":"0","code":"53","code_ascii":"5","confidence":"97"},"characater":{"poly":{"p":{"x":"1134","y":"640"},"p":{"x":"1139","y":"640"},"p":{"x":"1139","y":"664"},"p":{"x":"1133","y":"664"}},"bkcolor":"16777215","color":"0","code":"49","code_ascii":"1","confidence":"77"},"characater":{"poly":{"p":{"x":"1154","y":"639"},"p":{"x":"1163","y":"639"},"p":{"x":"1163","y":"663"},"p":{"x":"1153","y":"663"}},"bkcolor":"16777215","color":"0","code":"66","code_ascii":"B","confidence":"97"},"characater":{"poly":{"p":{"x":"1164","y":"638"},"p":{"x":"1173","y":"638"},"p":{"x":"1173","y":"663"},"p":{"x":"1163","y":"663"}},"bkcolor":"16777215","color":"0","code":"66","code_ascii":"B","confidence":"94"},"characater":{"poly":{"p":{"x":"1191","y":"637"},"p":{"x":"1206","y":"636"},"p":{"x":"1205","y":"660"},"p":{"x":"1190","y":"661"}},"bkcolor":"16777215","color":"0","code":"76","code_ascii":"L","confidence":"34"}},"det_time_us":"1072592","poly":{"p":{"x":"1088","y":"642"},"p":{"x":"1210","y":"634"},"p":{"x":"1210","y":"661"},"p":{"x":"1087","y":"669"}}}},"det_time_us":"1720812"}}} or on this link: https://drive.google.com/file/d/18wCzjMBpw7SIeVFByAGPQiqCBjg_0te3/view?usp=sharing
Now, that works fine but what I need is, to extract the .frames.frame.lps.lp.ncharacter from the JSON, too. I know I could simply do something like cat test.json | jq -r '.frames.frame.lps.lp.ncharacter'; in front of the above but that won't work as I need these commands to parse a huge file of JSON strings that are formatted as seen on the link and I need the .ncharacter parameter to show up in line with the extracted chars what means I would like to have an output like: ... X 99 Y 99 previous data formatted in the same way 8 1 97 5 89 4 97 5 97 1 77 B 97 B 94 L 34 6 following data formatted in the same way Z 99 ... Where the 8 on top is the .ncharacter parameter. I have tried: sed 's/},/},\n/g' test.json |awk '/"characater"/ { gsub("\"characater\"", "\"char" ++n "\"", $0) } 1'| jq -r '[.frames.frame.lps.lp.ncharacter],.frames.frame.lps.lp|.characters[]|[.code_ascii,.confidence]|@tsv' but that gives me jq: error (at :102): Cannot index array with string "characters" and I'm not sure why that is...
