curl | jq: parse error: Invalid numeric literal at line 2, column 0 - bash

Question

I have a simple bash file as below
#!/bin/bash
net=$(curl -s -H "Content-Type: application/json" -H "X-Auth-Token: $token" -d '{"network": {"name": "net1"}}' http://10.1.10.146:18090/network/v2.0/networks 2>&1 | awk '/id/{print $1}' | jq -r .network.id)
echo $net
Running this file gives me an error as below
parse error: Invalid numeric literal at line 2, column 0
tried making the changes according to these links
https://unix.stackexchange.com/questions/354943/setting-jq-output-to-a-bash-variable
Working with Bash and cURL
but nothing helped me, unable to figure out where i am going wrong. let me know the reason for the error and possible changes.
The curl output for the command
curl -s -H "Content-Type: application/json" -H "X-Auth-Token: $token" -d '{"network": {"name": "net1"}}' http://10.1.10.146:18090/network/v2.0/networks
output:
{"network":{"status":"ACTIVE","router:external":false,"availability_zone_hints":[],"availability_zones":[],"description":"","subnets":[],"shared":false,"tenant_id":"d0e75710820c401db3291ac6278f326f","created_at":"2018-05-15T07:37:42Z","tags":[],"ipv6_address_scope":null,"mtu":1450,"updated_at":"2018-05-15T07:37:42Z","admin_state_up":true,"revision_number":2,"ipv4_address_scope":null,"is_default":false,"port_security_enabled":true,"project_id":"d0e75710820c401db3291ac6278f326f","id":"1548df56-a35b-4232-9550-54a3c2266d60","name":"net1"}}
the idea is to get only the id from the output and store into a bash variable, to get the id i used the below command
curl -s -H "Content-Type: application/json" -H "X-Auth-Token: $token" -d '{"network": {"name": "net1"}}' http://10.1.10.146:18090/network/v2.0/networks 2>&1 | awk '/id/{print $1}' | jq -r .network.id
output:
be831582-90c1-499c-875f-9c0b0d1969a6
I have also tried removing the awk and parsing the curl json response, the same error is showing up.
thanks in advance.

The "parse error" message appears because the 2>&1 redirects any STDERR message into jq, which cannot parse it. Compare the output from these commands:
> curl http://no.such.host/network/v2.0/networks 2>&1
curl: (6) Could not resolve host: no.such.host
> curl http://no.such.host/network/v2.0/networks 2>&1 | jq '.'
parse error: Invalid numeric literal at line 1, column 4
Here are some ideas:
Separate all of the piped commands into separate commands.
Try adding set -x near the top of the script to "debug" all of the
commands.
Remove the 2>&1 because it is NOT helping you!
Add error handling to the separate commands.
We could help more if you provided the curl output. (We do not have HTTP access to the 10.1.10.146 host.)
