Web Service Connector: --data-urlencode in cURL command

I am attempting to use the following curl command to aggregate accounts, but getting a 406 error (ticket opened with SaaS company)

The curl command works fine in CLI( (bash/powershell). If i remove the --data-urlencode option - that works. its the --data-urlencode option that is causing the issue. This option is required so I can filter the results

curl --get --request GET 'https://api.url.com/user-management/queries/users/v1?offset=0&limit=500' --header 'Content-Type: application/json' --data-urlencode "filter=cid:'bd0xxxxxxfdba'"

Anyone have an tricks or ideas?
