MktoForms2.allForms() returning empty in local dev environment

hello

we have, somewhat customized marketo forms that we use via the javascript api.

 

now the code stopped working in local dev environment, I suspect it is related to this call:

 

Lukas_Meier_0-1593724685567.png

in written words: getForm?munchkinId=MYID&... returns 403 forbidden

 

basically I am getting a 403 and MktoForms2.whenReady never triggers

 

 

MktoForms2.allForms() returns []

 

this didn't use to be like that. This used to work.

 

Obviously, for local development, I use a virtual host e.g. mylocaldev.local

 

 

 

it still works in production, and it still works in staging as well where we use a subdomain of production

 

maybe I got black listed because I was "spamming" marketo with my local testing?

Re: MktoForms2.allForms() returning empty in local dev environment

it seems to work fine if I use a different browser

for example I just ran a test with opera, seems to pass and load the script

 

Why opera, well, they have an integrated vpn. It works without vpn activated though as well..

It's not you, it's the... questionable (I'm being nice)... policies of CloudFlare when they flag traffic as not regular-end-user-ish.

 

In this case probably because of the Referer. Also happens when using a debugging proxy, which they seem to fingerprint using other means. It's absolutely frustrating but the policy is controlled centrally.

Re: MktoForms2.allForms() returning empty in local dev environment

what would you recommend? create a virtual host of the prod domain for local dev? 

 

e.g. myproductivedomain.com as entry in my hosts file for dev environment?

That seems reasonable. I don't like to use actual localhost anyway.

Re: MktoForms2.allForms() returning empty in local dev environment

is there anything that works?

if I use a different virtual host, doesn't work either

 

If I directly access the URL of the script e.g.

http://app-lon09.marketo.com/index.php/form/getForm?munchkinId=...

 

then it works

it only doesnt't work, when i load the page to fill out the form

What browser + exact version are you using? CF tends to lag behind newer User-Agents as well.
