Office365.SendEmail' has an invalid value for parameter 'To

I receive this message "Office365.SendEmail' has an invalid value for parameter 'To" because I am using at OnSelect;

 

Office365.SendEmail(Gallery1.Selected.'E-Mail',"Thank you for visiting" , "You have been de-registered")

 

But not everyone fills in the e-mail field: Gallery1.Selected.'E-Mail' which causes the error.

 

How can I prevent the error without making the field a mandatory field?

Hi @SdR1,

 

An error message would be returned whenever a required parameter is blank in the function.

Please take a try with the following code which will send out the email without issues:

Add a button under the gallery and set its OnSelect property:

If(IsBlank(BrowseGallery1.Selected.EmployeeName.Email),"",Office365.SendEmail(BrowseGallery1.Selected.EmployeeName.Email,"test","details"))

Hi @v-yamao-msft

 

Did what you suggested and now have in the OnSelect of the Button;

 

If(IsBlank(Gallery1.Selected.'E-Mail'),"",Office365.SendEmail(Gallery1.Selected.'E-Mail',"Thank you for visiting" , "You have been de-registered"))

 

But I still receive the same error message.
