This works fine:


(make-process :name "my-proc2"
:buffer " *my-proc2*"
:command '("sh" "-c" "echo "hi"nsleep 10necho "there"")
:connection-type 'pipe
:filter (apply-partially 'my-pass-it-on-filter "/tmp/mytmprealtest"))


But if I use a variable like the code below I get Debugger entered--Lisp error: (wrong-type-argument stringp body):

(let ((body "echo "hi"nsleep 10necho "there from var""))
 (make-process :name "my-proc2"
 :buffer " *my-proc2*"
 :command '("sh" "-c" body)
 :connection-type 'pipe
 :filter (apply-partially 'my-pass-it-on-filter "/tmp/mytmprealtest")))

The variable should be a string as well, so why doesn't it work?

The documentation for make-process says:

...
:command COMMAND -- COMMAND is a list starting with the program file
name, followed by strings to give to the program as arguments.
...

The variable was a string as were all other arguments, so I'm not sure what is wrong.

You've quoted the list:

 :command '("sh" "-c" body)

So you have passed it a symbol body not the string value of the variable.

Try:

 :command (list "sh" "-c" body)

or:

 :command `("sh" "-c" ,body)

Either of which cause body to be evaluated to its string value.
