Hi,
i tried to install neu Plugin (cliffparnitzky/form-dependent-mandatory-field), but two days I have the same error:
Code:
12:24:29 ERROR     [console] Error thrown while running command "cache:warmup --env=prod --no-ansi". Message: "Call to a member function isXmlHttpRequest() on null" ["exception" => Error { …},"command" => "cache:warmup --env=prod --no-ansi","message" => "Call to a member function isXmlHttpRequest() on null"]
In BaseWidget.php line 59:
                                                        
  Call to a member function isXmlHttpRequest() on null
I use last Contao 4.10.3.
Anyone had a similar problem?
