Unable to send email from flow

Hello everyone, 

 

I am trying to setup flow which send email with mail attachment. 

 

I setup a template which send a new file from OneDrive to email, after it's created in OneDrive.

The first step is ok, but when the flow have to send email i get this: 

 

"Unable to process template language expressions in action 'Send_Email' inputs at line '1' and column '2070': Function language template EncodeBase64 expected its parameter to be a string, object, or field. The provided value is of type 'Null'.

 

Thank you

Hi @hanaunarova,

 

Which template you are working with?

Would you please share a screenshot of the scenario you mentioned, specially the Input part which show the error messages under the send an Email Action?

Error message

"

Function language template EncodeBase64 expected its parameter to be a string, object, or field. The provided value is of type 'Null'.

"

means the value you provided to the corresponding field is null, means it contains nothing, while currenlty Microsoft Flow is not available to handle contents which value is null.

 

Regards,

Michael
