How can I disable ellipsis in backtraces?

Question

I have these lines:

;default 12
(setq eval-expression-print-length 0)
;default 4
(setq eval-expression-print-level 0)

(setq backtrace-verbose t)
(setq debugger-args '("--no-debugger-ellipsis"))

, but I'm still seeing this:

Debugger entered--Lisp error: (error "Could not find package openai. Updating recipe rep...")
  error("Could not find package %S. Updating recipe reposit..." openai (org-elpa melpa gnu-elpa-mirror nongnu-elpa el-get emacsmirror-mirror))
