exporting and then importing results in `the server does not support credential metadata, requires >= 2.6.x` error

[jtarchie]

What version of the credhub server you are using?

1.9.3

What version of the credhub cli you are using?

$ credhub --version
CLI Version: 2.8.0
Server Version: 0.0.0

If you were attempting to accomplish a task, what was it you were attempting to do?

With the current CLI (2.8.0), when we credhub export and then credhub import we receive an error on many credentials of the server does not support credential metadata, requires >= 2.6.x. It appears that the export includes an empty field for each credential of metadata: {}. The import is then not able to use this and errors on the import.

What did you expect to happen?

Not to receive this error. Most likely, credhub export would export a field that is unsupported by the server it is exporting from.

What was the actual behavior?

This error message on every credential trying to be imported -- the server does not support credential metadata, requires >= 2.6.x

The 2 that we manually added, which did not have the metadata: {} worked. As can be seen in the following output.

Example output:

Import complete.
