Sometimes when doing a VS recording using Curl with Expect:100-Continue headers, recorder do not capture any transactions.
Supported DevTest environments.
CURL automatically adds an Expect: 100-Continue header if the payload is bigger than 1024 bytes which is causing the issue.
Explicitly disabling the Expect:100-Continue header as below in the CURL command should resolved the issue.
curl -H 'Expect:'
