401 invalid token / handler.xsrf_token does not match with the cookie

Question

we are stuck in the dbauth module:

Symptoms: While signup, the user is created BUT:

• The server does not send mail
• Response received is 401 Invalid Token

Diagnosis Steps:

• Started with scratch
• Made a new Gramex project from scratch
• Populated the template register.html

<form method="POST" action="" autocomplete="on" class="regForm">
  <div class="form-content">
    <div class="">
      <div class="col-md-12">
        <input type="hidden" name="_xsrf" value="{{ handler.xsrf_token }}">
        <div class="form-group">
          <input type="text" name="fname" id="fname" class="form-control" size="100" placeholder="Your First Name *" value="" />
        </div>
        <div class="form-group">
          <input type="text" name="lname" id="lname" class="form-control" size="100" placeholder="Your Last Name *" value="" />
        </div>
        <div class="form-group">
          <input type="email" name="user" class="form-control" id="email" placeholder="Your Email ID *" value="" required />
        </div>
        <div class="form-row">
          <div class="form-group col-md-12">
            <select class="form-control" name="industry" id="industry">
              <option selected>Retail</option>
              <option>Energy and Resources</option>
              <option>Financial Services</option>
              <option>Transportation</option>
              <option>Others</option>
            </select>
          </div> <!-- form-group end.// -->
        </div>
      </div>
    </div>
    <div class="col-md-12">
      <button type="submit" class="btnSubmit">Submit</button>
    </div>
  </div>
</form>

• auth.csv looks like

fname,lname,user,industry,password

• Tested

Findings:

• xsrf token (That is fetched from handler.xsrf_token and stored in the form in a hidden field) does not match the xsrf token in the cookie

Questions:

• Is there a simpler way?
• This issue is created even when we run the code copied from the documentation, So my guess is, this has something to do with generation of xsrf or may be session creation. Not sure, appreciate any inputs.
• Do we have another project that is running and available to refer?
• Do you have a direct solution to this?

Answer 1

Since user is created, there is no problem with xsrf token. Issue seems to be with sending mail. Make sure email service gramex-guide-email is defined.

Invalid Token error occurs when AuthHandler cannot find signup key. In your gramex.yaml, update signup configuration to

signup:
  key: signup
  template: $YAMLPATH/register.html
  columns:
    user: user
    fname: fname
    lname: lname
    industry: industry
