I'm doing a GET request with rails/ajax and it works fine with 1 parameter, but when I add more it throws an error at me and I can't figure out why.

The following code gives me: Uncaught Error: Syntax error, unrecognized expression: # at Function.Sizzle.error

function setSelectOptions(sheetTemplateColumn, sheetTemplateItemId) {
  // eslint-disable-next-line no-undef
  Rails.ajax({
    url: `/sheet_templates/extra_options?option=${sheetTemplateColumn}&sheet_template_item_id=${sheetTemplateItemId}`,
    type: "GET",
    dataType: "json"
  });
}

In my rails server logs there are no errors, the request is fine:

Started GET "/sheet_templates/extra_options?option=item_number_free_field8&sheet_template_item_id=32"

Processing by SheetTemplatesController#extra_options as JSON

Parameters: {"option"=>"item_number_free_field8", "sheet_template_item_id"=>"32"}

...

Since the javascript is giving an error it stops running the rest of the script.
