Issue/Introduction:

Sometimes when doing a VS recording using Curl with Expect:100-Continue headers, recorder do not capture any transactions.

Cause:

CURL automatically adds an Expect: 100-Continue header if the payload is bigger than 1024 bytes which is causing the issue.

Environment:

Supported DevTest environments.

Resolution:

Explicitly disabling the Expect:100-Continue header as below in the CURL command should resolved the issue.
curl -H 'Expect:'
