Unable to login with SSO neither with username/password

[vladaman]

After enabling SSO for testing I can’t log in. Neither with SSO or Username/password.

When using SSO I get an error:

string.replace is not a function
*string.replace is not a function*

When I click on email login I get: " SSO is enabled, please log in with SSO"

Is there any way to log in?

I found the issue is here:

var escape = module.exports = function escape(string, ignore) {
  var pattern;

  if (string === null || string === undefined) return;

  ignore = (ignore || '').replace(/[^&"<>\']/g, '');
  pattern = '([&"<>\'])'.replace(new RegExp('[' + ignore + ']', 'g'), '');
  // TODO bug here, string is an object
  return string.replace(new RegExp(pattern, 'g'), function(str, item) {
            return escape.map[item];
          })
}

var map = escape.map = {
    '>': '&gt;'
  , '<': '&lt;'
  , "'": '&apos;'
  , '"': '&quot;'
  , '&': '&amp;'
}

Hello, I hope you are well.

Check this solution below.

var escape = module.exports = function escape(string, ignore) {
var pattern;

if (string === null || string === undefined) return ‘’;
string = String(string); // Ensure string is a string

ignore = (ignore || ‘’).replace(/[^&“<>']/g, ‘’);
// Escape special characters in the regex
var escapedIgnore = ignore.replace(/[-{}()*+?.,\^$|#\s]/g, ‘\$&’);
pattern = '([&”<>'])‘.replace(new RegExp(’[’ + escapedIgnore + ‘]’, ‘g’), ‘’);

return string.replace(new RegExp(pattern, ‘g’), function(str, item) {
return escape.map[item];
});
};

var map = escape.map = {
‘>’: ‘>’,
‘<’: ‘<’,
“'”: ‘'’,
‘"’: ‘"’,
‘&’: ‘&’
};

@vladaman did you have any luck with a solution here? i’m having the same issue. i’m using the docker image for n8n v1.89.2

was hoping to stick to the image and not have to deal with internal packages
