Fix topic name parsing

[facucc]

The value of the topic name variable is taking the value of the topic name + payload
The error is in the line 1448

Example:

• TopicName --> $aws/things/test/jobs/start-next/accepted{"clientToken":"test","timestamp":1712955349}

Must be

• TopicName --> $aws/things/test/jobs/start-next/accepted

Hello @facucc,

Thank you for reaching out to us.

The topic name pointer (pPublishInfo->pTopicName) returned by the code is NOT NULL terminated. Your application must use the topic name length (pPublishInfo->topicNameLength) to determine where does the topic end.

This is done to reuse the existing payload memory instead having to copy it to a different string in order to NULL terminate it.

Does that answer your question? Or are you saying that the topic name length variable is set incorrectly so that you are reading into the payload?

Thanks,
