I added the following:
sslproxy_cert_error allow all
sslproxy_flags DONT_VERIFY_PEER
sslproxy_flags DONT_VERIFY_PEER
and it works now.
In my access.log:
172.16.84.241 - - [21/Nov/2019:15:15:05 -0500] "CONNECT static.xx.fbcdn.net:443" 200 4199 "-" "Mozilla/5.0 (Windows NT 10.0; WOW64; Trident/7.0; rv:11.0) like Gecko"

So since I am new to sslbump, what am I benefiting from this? Will I be able to see unencrypted data?
Thanks

Is your signing certificate (i.e. wildcardcert.pem) a CA certificate? If
not, then you cannot use it to sign other certificates. SslBump with
dynamic certificate generation requires a CA certificate to sign the
generated certificates.
CA certificates have a "true" CA basic constraint:
$ openssl x509 -in wildcardcert.pem -noout -text | \
grep -A1 'Basic Constraints'
X509v3 Basic Constraints:
CA:TRUE
If they are CA certificates, did you import them into the browser/OS
trusted certificates store? In most environments, a browser will not. by
default, trust a CA certificate that Squid can use to sign dynamically
generated certificates.
