Call API with curl gives 417 error

Hello at all,

I’m trying to create a client script in PHP using curl to call REST API from Frappe / ERPNext.
This is working great with GET, but PUT or POST gibts me 417 error. I’m using v14

My system setup is as follow:

  • Linux Server with Ubuntu and Apache
  • my PHP script using Apache with SSL and http2
  • Frappe / ERPNext is installed locally without Docker
  • Frappe / ERPNext is using built-in nginx on port 8080
  • server uses two domains:
  • both sites uses SSL certificate
  • crm.mysite.com also Apache with this proxy config:
ProxyRequests Off
ProxyTimeout 120
ProxyPass "/.well-known/" "!"
ProxyPass "/AutoDiscover/" "!"
ProxyPass "/mail/" "!"
ProxyPass "/cgi-bin/" "!"
ProxyPass "/assets/" "!"
ProxyPass "/files/" "!"

RewriteEngine On
RewriteCond %{REQUEST_URI}  ^/socket.io               [NC]
RewriteCond %{QUERY_STRING} transport=polling         [NC]
RewriteRule /(.*) http://localhost:9000/socket.io/$1  [P,L]
RequestHeader set Host "crm.mysite.com"
RequestHeader set X-Frappe-Site-Name "crm.mysite.com"
ProxyPass "/socket.io" "http://localhost:9000/socket.io/"
ProxyPassReverse "/socket.io" "http://localhost:9000/socket.io/"

<Location "/socket.io">
	RequestHeader set X-Frappe-Site-Name "crm.mysite.com"
</Location>

Alias "/assets" "/home/frappe-user/frappe-bench/sites/assets"
<Directory /home/frappe-user/frappe-bench/sites/assets>
	Options FollowSymLinks
	Require all granted
</Directory>
Alias "/files" "/home/frappe-user/frappe-bench/sites/crm.mysite.com/public/files"
<Directory /home/frappe-user/frappe-bench/sites/crm.mysite.com/public/files>
	Options FollowSymLinks
	Require all granted
</Directory>

ProxyPass "/"  "http://localhost:8080/"
ProxyPassReverse "/"  "http://localhost:8080/"
<Location "/">
	RequestHeader set X-Frappe-Site-Name "crm.mysite.com"
</Location>

If I call the API with PUT or POST then I get 417.
When I use “curl -I -L https://mysite.com” gives HTTP/2
“curl -I -L https://crm.mysite.com” gives HTTP/2
“curl -I -L 127.0.0.1:8080” gives HTTP/1.1

So my question is: how to put the built-in nginx from Frappe to http2?
If I change the config from “listen 80;” to “listen 80 http2;” then the server does not start.

I also tried my curl script to add a new header:

    $header     = ['Content-Type' => 'application/json',
                              'Accept' => 'application/json',
                              'Expect' => ''];

Does anyone have an idea?

Thanks,
Tobias
