Error when exporting LaTeX

Error when exporting LaTeX

[Peter Davis]

I'm writing a fairly simple document with some #+BEGIN_SRC/#+END_SRC
blocks, and when I try to export to LaTeX/PDF, I get:

org-latex-src-block: Wrong type argument: stringp, nil

Does this ring any bells? I can try to cobble together a "neutralized"
sample to reproduce the problem, but I thought I'd see if anyone
recognized it.

Thanks,

Ok, here's a sample file and image that reproduces the problem. Any help
appreciated.

Thank you.

* Overview

Many applications using the XYZCo API will follow a sequence of operations like this:

** User logs in, establishing identity and access privileges

The login page is invoked via an http request, such as:

#+BEGIN_SRC js
GET http://local.xyzco.com:3000/sample/login
#+END_SRC

In the Sample App, this results in a page showing four buttons:

** Login with XYZ

If the user selects "Login with XYZ", the Sample App invokes this URL:

#+BEGIN_SRC
GET http://local.xyzco.com:3000/sample/auth/xyz
#+END_SRC

The response, 302, results in a redirect to a new page prompting for username and password is presented[1]:

#+BEGIN_SRC js
GET http://sandbox.api.xyzco.com:8080/openid-connect/v2/authorize?response_type=code&redirect_uri=http%3A%2F%2Flocal.xyzco.com%3A3000%2Fsample%2Fauth%2Fxyz%2Fcallback&scope=openid&client_id=152ced50-1369-4b19-8b26-8f3d5d9bfd6a.xyzco.com
#+END_SRC

[[./pd-logo-jelly-small.gif]]

Entering a username and password here results in this request:

#+BEGIN_SRC js
POST http://sandbox.api.xyzco.com:8080/openid-connect/j_spring_security_check?response_type=code&redirect_uri=http%3A%2F%2Flocal.xyzco.com%3A3000%2Fsample%2Fauth%2Fxyz%2Fcallback&scope=openid&client_id=152ced50-1369-4b19-8b26-8f3d5d9bfd6a.xyzco.com
#+END_SRC

[[./pd-logo-jelly-small.gif]]

** The application provides security information (e.g., OAuth2 token) to enable access to information

#+BEGIN_SRC js
GET http://sandbox.api.xyzco.com:8080/openid-connect/v2/authorize?response_type=code&redirect_uri=http%3A%2F%2Flocal.xyzco.com%3A3000%2Fsample%2Fauth%2Fxyz%2Fcallback&scope=openid&client_id=152ced50-1369-4b19-8b26-8f3d5d9bfd6a.xyzco.com
#+END_SRC

#+BEGIN_SRC js
GET http://local.xyzco.com:3000/sample/auth/xyz/callback?code=eyJhbGciOiLlif_vla6jwjA ...
#+END_SRC

From this point, the application can present other options to the user.

[1] If the user is not already logged in, he or she will see the login page

It looks like you forgot to give a language (you cannot have
a "#+begin_src" with no language).

Ah! Yes, I missed one. That seems to have fixed it.

Thank you.
