Not receiving tweets using source connector

**Describe the bug**
I created twitter source connector as per the documentation and I am not receiving any tweets in the topic tweets

**To Reproduce**
Steps to reproduce the behavior:
./pulsar-admin source create --name twitter --source-type twitter --destinationTopicName tweets --source-config '{"consumerKey":"xxxxxxxx","consumerSecret":"xxxxxxxxxxxxxxx","token":"xxxxxxxxxxx","tokenSecret":"xxxxxxxxxxxxxxx"}'

**Expected behavior**
should receive tweets in the topic "tweets"

**Desktop (please complete the following information):**
- OS: [e.g. iOS]

**Additional context**
Add any other context about the problem here.

Start with the provided `pulsar-admin source create` command and the Twitter source connector configuration, then check how the connector publishes to the `tweets` topic. Done means the configured Twitter source receives tweets and they appear in that topic; the issue does not name a source file or test.
