c# - Sendgrid System.ArgumentException: Unknown element: html -


i've update following packages latest version:

a) sendgrid.smtpapi updated 1.3.1

b) sendgrid update 6.0

and webtransport.deliver method not there anymore - no problem, i've switched deliverasync method strange error, it's supposed fixed since 2 years ago:

system.argumentexception: unknown element: html

this part of stack trace can of interest:

system.argumentexception: unknown element: html

at sendgrid.errorchecker.checkforerrors(httpresponsemessage response, stream stream)

at sendgrid.errorchecker.d__0.movenext()

--- end of stack trace previous location exception thrown ---

at system.runtime.compilerservices.taskawaiter.throwfornonsuccess(task task)

at system.runtime.compilerservices.taskawaiter.handlenonsuccessanddebuggernotification(task task)

at sendgrid.web.d__0.movenext()

--- end of stack trace previous location exception thrown --- @ system.runtime.compilerservices.taskawaiter.throwfornonsuccess(task task)

and how email sending code looks like:

sendgridmessage emailmessage = new sendgridmessage(); emailmessage.addto(user.completeregistrationmodel.useremailaddress); emailmessage.from = new mailaddress(configurationhelper.emailsenderaddress, configurationhelper.emailsendername); emailmessage.enabletemplateengine(configurationhelper.confirmationemailtemplateid); emailmessage.addsubstitution("-urlaplicatie-",                 new list<string>()                 {                     string.format("{2}{0}{1}", user.completeregistrationmodel.companyurlprefix,                         configurationhelper.domainsuffix, configurationhelper.applicationaccessprotocol)                 });             emailmessage.addsubstitution("-username-",                 new list<string>() {user.completeregistrationmodel.useremailaddress});             emailmessage.addsubstitution("-confirmationurl-",                 new list<string>() {user.completeregistrationmodel.useremailaddressconfirmationcompleteurl});              emailmessage.subject = string.format("{0}{1}", user.completeregistrationmodel.companyurlprefix,                 configurationhelper.domainsuffix);             emailmessage.text = " ";             emailmessage.html = " ";              web webtransport =                 new web(new networkcredential(configurationhelper.sendgridusername,                     configurationhelper.sendgridpassword));              try             {                 await webtransport.deliverasync(emailmessage);             }             catch (invalidapirequestexception exception)             {                 elmah.errorsignal.fromcurrentcontext().raise(exception);             }
