Unable to include non-string env vars

[ipsi]

If I have an env section like:

env:
  SKIP_SSL_VALIDATION: true

Then I get the following error:

java.lang.ClassCastException: java.lang.Boolean cannot be cast to java.lang.String

I would not expect that error. It can be worked around by quoting the manifest value, e.g.

env:
  SKIP_SSL_VALIDATION: "true"

I also got the same issue.
Did anyone got the solution for this?
