The Python SDK attempts to read the activation key from the
~/.streamsets/activation/rsa-signed-activation-info.properties
file at runtime.
This error means that part of the activation key itself is malformed: either the
file's contents are malformed, or the file itself is malformed/corrupted.
Please verify that the structure of the key within the file is what the Python SDK expects
it to be - it should look like the following:
--------SDC ACTIVATION KEY--------
<ACTIVATION KEY HERE>
--------SDC ACTIVATION KEY--------
If the `SDC ACTIVATION KEY` string is missing, either before or after the
literal activation key, it can lead to an error like this.
Double-check the file contents, and make sure it's formatted correctly.
