Receiving "message":"CB-ACCESS-KEY header is required" when attempting to connect to coinbase pro api - coinbase-api

Question

I have been trying to mock up a cli script to connect to the coinbase pro api.
I have been able to get it to work successfully using python but I am looking to have a cli-based solution.
#!/bin/bash
path="/accounts/"
body=""
function make_request(){
method="$1"
requestpath="$2"
body="$3"
timestamp=$(date +%s)
api_key=$(head -n 1 ./api_key)
sec_key=$(head -n 1 ./sec_key)
passphr=$(head -n 1 ./passphrase)
hmac_key=$(echo -n $sec_key | base64 -d)
message="$timestamp$method$requestpath$body"
# create a sha256 hmac with the secret
signature_b64=$(echo -n $message | openssl dgst -sha256 -hmac $hmac_key -binary | base64)
user_agent="Mozilla/5.0 (X11; Linux i686; rv:59.0) Gecko/20100101 Firefox/59.0"
url="https://api.pro.coinbase.com"
## Build Header info ##
cont_type="'Content-Type': 'Application/JSON'"
accpt_enc="'Accept-Encoding': 'gzip, deflate'"
head_sign="'CB-ACCESS-SIGN': '"$signature_b64"'"
head_time="'CB-ACCESS-TIMESTAMP': '"$timestamp"'"
head_key="'CB-ACCESS-KEY': '"$api_key"'"
head_pass="'CB-ACCESS-PASSPHRASE': '"$passphr"'"
# data=$( curl -v \
# -A "$user_agent" \
# -H "$head_key" \
# -H "$cont_type" \
# -H "$head_sign" \
# -H "$head_time" \
# -H "$head_pass" \
# "$url$path" )
data=$( wget --verbose \
--debug \
--user-agent="$user_agent" \
--header="$head_key" \
--header="$cont_type" \
--header="$head_sign" \
--header="$head_time" \
--header="$head_pass" \
"$url$path" )
echo $data
}
make_request GET "$path" "$body"
I get the same error whether I use curl or wget.
I am not sure what is going on.
I have compared my headers from debug and verbose and they appear to be simmilar to me to my python headers.
Example python headers:
/accounts/
{'User-Agent': 'python-requests/2.20.0', 'Accept-Encoding': 'gzip, deflate', 'Accept': '*/*', 'Connection': 'keep-alive', 'Cookie': '__cfduid=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx', 'Content-Type': 'Application/JSON', 'CB-ACCESS-SIGN': 'Gk+xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx=', 'CB-ACCESS-TIMESTAMP': '1592491810.1017096', 'CB-ACCESS-KEY': 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx', 'CB-ACCESS-PASSPHRASE': 'xxxxxxxxxxx'}
wget headers:
