After we upgraded our self hosted version of Mautic (to the latest 2.2.0) we encounter a problem when posting form data directly to our Mautic instance.  
  
We have a form defined with emailaddress and company name, and post data via Python:  
  
data = {‘mauticform[company\_name]’: ‘Test’, ‘mauticform[formId]’: 18, ‘mauticform[partner\_email]’: ‘florus+test2@{custom\_domain}.nl’}  
  
requests.post(‘https://{custom\_mautic\_domain}/form/submit’, data=data)  
  
  
  
Response is 500.  
  
  
  
And here are the last lines of the log file (after posting):  
  
[2016-10-17 11:33:13] mautic.ERROR: Deprecation: The alias option of the form.type\_extension tag of service “fos\_rest.form.extension.csrf\_disable” is deprecated since version 2.8 and will be removed in 3.0.

Couple of observations: firstly the latest version is 2.2.1, which version do you have? Were there any errors during the installation?

Secondly, the timestamp on that first error is a couple of hours later than all the warnings, so I reckon your problem is to be found there. At a guess I’d say that file hasn’t been updated while others have, but you could take a look at line 67 and see if there’s something you can change like it says (but that may just lead to a different error further down the line)
