csv--compute-header-string error

[fountainer]

When I print data, e.g., mtcars, the data is displayed. However, there is an error csv--compute-header-string (wrong-type-argument number-or-marker-p nil). The backtrace is as follows:

Debugger entered--Lisp error: (wrong-type-argument number-or-marker-p nil)
  jit-lock--run-functions(69 137)
  jit-lock-fontify-now(69 137)
  csv--compute-header-string()
  csv--header-string()
  eval((csv--header-string))
  redisplay_internal\ \(C\ function\)()

By the way, I can use csv-mode with no errors.

I'm trying to find a solution. It might be due to the timing of calcuating the header.
