Showing semi column error but not find any semicolumn missing

The code provided in the question seems to be missing a closing brace for the submit method. This could be causing the semicolon error. Here's the corrected code:

submit(saveClicked) {
  var self = this;
  var form_data = new FormData(self.$refs.signupForm);

  self.$http
    .post(self.$member_whitelist_signup, form_data)
    .then(function (response) {
      if (response.data.success == true) {
        if (saveClicked == true) {
          self.$router.replace({ path: 'google.com' });
        } else {
          self.$router.replace('yahoo.com');
        }
      } else {
        if (response.data.data == null) {
          self.error_msg = response.data.message;
        } else {
          let first_error_key = Object.keys(response.data.data)[0];
          self.error_msg = response.data.data[first_error_key][0];
        }
      }

      self.devloader = false;
    })
    .catch(function (error) {
      console.warn(error);
    });
}, // <-- add this closing brace

Make sure to check the rest of your code for any other missing or misplaced braces or semicolons.
