Remember to cover the basics, that is, what you expected to happen and
what in fact did happen.  You don't know how to make a good report?  See

I noticed that I cannot run C-c C-c to convert plantuml source blocks
since the commit (4e854974be9788f029f2d73f829c4d51d2b83faf), see changes

https://code.orgmode.org/bzg/org-mode/commit/4e854974be9788f029f2d73f829c4d51d2b83faf#diff-9c9a333463276ff17be763269a5042f92a40817R73

If I have a simple source block as such as:
#+BEGIN_SRC plantuml :file output.png
@startuml
actor Foo1
actor Foo2
Foo1 -> Foo2 : Test
@enduml
#+END_SRC

When I try to run C-c C-c I receive the following error message:
org-babel-execute-src-block: Wrong type argument: char-or-string-p, nil

During my debugging I found out that assignments inside the function
org-babel-plantuml-make-body returns nil and that causes the function to
return nil which is not expected behavior. I remember this working
before, so I went looking through the history and noticed the addition
of this code. To me it looks like the logic is wrong. As the expression:
(org-babel-variable-assignments:plantuml params)

Could not possibly not return the body and without the body the content
will be invalid. I have verified that reverting this commit fixes the
issue and lets me generate PlantUML files.

  I started using plantuml in org last week (and am enjoying it greatly),
  so take this with a hint of salt from a beginner. Still, at least in my
  installation, your source code block works fine without '@startuml' and
  '@enduml':
  
  #+BEGIN_SRC plantuml :file output.png
  actor Foo1
  actor Foo2
  Foo1 -> Foo2 : Test
  #+END_SRC
  
  All the best,
  
  Jarmo
