What Operating System are you using (both controller, and any agents involved in the problem)?

Ubuntu 20

Reproduction steps

1. Create a freestyle job
2. Check the box for Vault plugin
3. Provide Vault path and credentials
4. Provide secrets path
5. Store the secret in a variable
6. Use script to echo the variable

Expected Results

Expected the job to run and use the credentials pulled. Confirmed the paths are correct (as they can be pulled from the same API URI outside of Jenkins).

Actual Results

The job failed due to being unable to get credentials.

Console output:
