Cannot coerce String { class: java.lang.String }

I am trying to send email from the flow and stored all the email addresses in the yaml file like below

# Email
email:
  toEmail: "abc.123@gg.org,def.456@gg.org"
  fromEmail: "ms-dev@gg.org"
  ccAddress: "abc123@gmail.com"

I am trying use the above values in to the send email connector like

enter image description here

<email:send doc:name="Send" doc:id="fd09c56f-eaed-44c4-ab06-aa0417f2fdbf" config-ref="Email_SMTP" subject="Error with SOW integration between D365 and Salesforce " fromAddress='#[p("email.fromEmail")]' toAddresses='#[p("email.toEmail") splitBy ","]' ccAddresses='#[p("email.ccAddress")]'>
            <email:body contentType="text/html">
                <email:content ><![CDATA[#[vars.emailBody]]]></email:content>
            </email:body>
        </email:send>

But when debugging Iam getting the error like below

org.mule.runtime.core.internal.exception.OnErrorPropagateHandler: 
********************************************************************************
Message               : "Cannot coerce String { class: java.lang.String } ("abc123@gmail.com" as String {class: "java.lang.String"}) to Array" evaluating expression: "p("email.ccAddress")".

After fixing ccAddresses error I get below error

Can anyone please suggest what is that I am missing here.

Solution

  • The problem is that ccAddresses expects an array. Because you are using an expression to configure that attribute you need to convert the string value from the configuration file explicitly to an array, for example using the splitBy() function as you did in toAddresses.

    Or if you will only use one address simply remove the expression and use a property placeholder (ccAddresses="${email.ccAddress}").
