Hello,
We are experiencing an issue with the automatic sending of SMS through the platform connected to Releans. Below is the error message indicated in the plugin:
Last SMS Response
{"name":"PHP Notice","message":"Undefined property: stdClass::$details","code":8,"type":"yii\\base\\ErrorException","file":"/var/www/html/releansstep/common/components/SMS.php","line":1484,"stack-trace":["#0 /var/www/html/releansstep/common/components/SMS.php(1484): yii\\base\\ErrorHandler->handleError()","#1 /var/www/html/releansstep/common/components/SMS.php(450): common\\components\\SMS->verifyNumber()","#2 /var/www/html/releansstep/frontend/modules/api2/controllers/MessageController.php(171): common\\components\\SMS->sendMessage()","#3 [internal function]: app\\modules\\api2\\controllers\\MessageController->actionSend()","#4 /var/www/html/releansstep/vendor/yiisoft/yii2/base/InlineAction.php(57): call_user_func_array()","#5 /var/www/html/releansstep/vendor/yiisoft/yii2/base/Controller.php(178): yii\\base\\InlineAction->runWithParams()","#6 /var/www/html/releansstep/vendor/yiisoft/yii2/base/Module.php(552): yii\\base\\Controller->runAction()","#7 /var/www/html/releansstep/vendor/yiisoft/yii2/web/Application.php(103): yii\\base\\Module->runAction()","#8 /var/www/html/releansstep/vendor/yiisoft/yii2/base/Application.php(384): yii\\web\\Application->handleRequest()","#9 /var/www/html/index.php(17): yii\\base\\Application->run()","#10 {main}”]}
We are unable to determine whether the issue is related to your plugin or Releans itself. Could you please provide guidance on how to resolve the problem?
Thank you for your assistance.
