The code to build email action:

```
EmailTemplate.Builder emailBuilder = EmailTemplate.builder();
emailBuilder.to(receivers);
emailBuilder.subject(subject);
String bodyTemplate = ResourceUtils.readResourceToString("error-message-email-body-template.html");
emailBuilder.htmlBody(bodyTemplate);
EmailAction.Builder emailActionBuilder = EmailAction.builder(emailBuilder.build());
emailActionBuilder.setAttachPayload(DataAttachment.YAML);
return emailActionBuilder;

```

Both ES and watcher are `2.0.0-rc1`.

We've just released the GAs for ES and Watcher 2.0, have you tried with those?

Thanks your advice but I upgrade both elasticsearch and watcher to 2.0.0（without `rc1`, sure）, it still gives:

I find that error always occurs despite of which type(JSON or YAML) of attachment of the mail. Even no attachment still encountered that error.

I google about that, some guys say that the cause of that problem is the version of java mail library. But as you know, Watcher is not a open source plugin, so it's hard for me to figure out what goes wrong in mail module of Watcher.

I Upgraded Watcher and ES to `2.0.0-rc1`(then `2.0.0` after GA released) on Monday , but just couldn't send a mail successfully up to now, this Friday. I'm under a lot of stress because a team waiting this feature for a week. I can't roll back ES to 1.7 because another team wants Kibana `4.2.0`(custom name for filter, a great feature) badly.

Really looking-forward a reply from you official guys.

Look at what they suggested in this thread: [UnsupportedDataTypeException when trying to send email](https://discuss.elastic.co/t/unsupporteddatatypeexception-when-trying-to-send-email/28634/6)

This worked for me on the latest watcher, and ES 2.0.0 Stable:

```
$ cd /usr/share/elasticsearch/plugins/watcher/
    $ sudo mv activation-1.1.1.jar ../../lib/
    $ sudo mv javax.mail-1.5.3.jar ../../lib/
    $ sudo service elasticsearch restart
```

@kurtcoke Thanks for the concise workaround. I have faced this on a Windows environment ES 2.0 GA, and the workaround was very useful.

Hey,

just a quick heads up. This is fixed in Elasticsearch 2.0.2 and 2.1.1 and does not require any workarounds any more.
