Issue with remove file

[Jeremy_Bepoix]

Hello,

I’ve got some issue for remove file with Code node.

VAR : NODE_FUNCTION_ALLOW_BUILTIN well setted

Code :

const fs = require('fs');
var stdout = ""

const path = "G:/library/userpref.blend";
if(fs.existsSync(path)){
  fs.unlink(path)
  stdout = "File remove"
}else{
  stdout = "File not found"
}

return [{json : { "stdout": stdout}}];

error :

ERROR: Unknown error [line 6]

TypeError [ERR_INVALID_ARG_TYPE]: The "cb" argument must be of type function. Received undefined

Have you got an idea ?

regards,

• n8n version: 0.202.1
• Database you’re using (default: SQLite):
• Running n8n via npm

Hello,

no one has encountered this problem?

Sorry for the noise…I was not well awake
it was simple missing call back

do not,

if(fs.existsSync(path)){
  fs.unlink(path)
  ...

but do

fs.unlink(deleteFile, function (err) {
  if (err) {
   ...
