Save tree view json to file using jq library - json

Question

I have like this json data in my case:
sshpass -p $PASSWORD ssh -o StrictHostKeyChecking=no $LOGIN /bin/bash -s << EOT
echo "Saving to file.."
USER_DATA="{\"id\":"$USER_ID",\"sha\":"$USER_SHA"}"
echo "{\"id\":"$PRODUCT_ID",\"user\":"$USER_DATA"}" | jq -re > ~/user.json
EOT
When I tried save this json to file get error with message:
parse error: Unmatched '}' at line 1, column 21
How I can save correctly my json data to file?

You should use jq to create your json. Try something like this :
sshpass -p $PASSWORD ssh -o StrictHostKeyChecking=no $LOGIN /bin/bash -s << EOT
echo "Saving to file.."
jq --arg id "$PRODUCT_ID" -n '{$id}' | \
jq --arg id "$USER_ID" \
--arg sha "$USER_SHA" \
--arg user "user" \
'.[$user]={$id, $sha}' > ~/user.json
EOT
Explanations:
--arg id "$PRODUCT_ID" : create a variable for jq, called id which contains the value taken from $PRODUCT_ID
-n '{$id}' : create a new json template
This will take the variable name as well as its value
Here, this creates the json {id : $id}
jq ... | jq ... : we pass the output of the 1st jq command as the input of the 2nd command
'.[$user]={$id, $sha}' : we add new elements to the input
.[$user] : the element name from the $user variable
{$id, $sha} : will create an object from the variables, i.e. {id : $id, sha : $sha}
the whole command creates the element : user : {id : $id, sha : $sha}
