The error message is generated when the browser cannot resolve a URL. In Conga, this is generally caused by a malformed URL in your Composer button.

Typical causes can include:

  • Spaces within the URL
  • Spaces at the end of the URL
  • Missing an ampersand (&) between parameters
  • Using a URL pointing to an invalid server (such as beta vs. www)

What to Do

Remove all spaces from the button's URL. Use plus signs instead of spaces in a parameter. Plus signs render as spaces in the Composer merge operation, but do not lead to 404 authorization errors.
