I'm running my gmail add-on with the following scopes:
https://mail.google.com/
https://www.googleapis.com/auth/gmail.addons.execute
https://www.googleapis.com/auth/gmail.addons.current.action.compose
https://www.googleapis.com/auth/gmail.addons.current.message.metadata
https://www.googleapis.com/auth/script.external_request
I have a button, and corresponding compose action event, that is supposed to read recipient, subject, and body information from some input fields and insert this info into the compose UI.
The compose action callback looks like this:
function autofillEmailDraft(e) {
var recipient = e.formInput.recipient;
var subject = e.formInput.subject;
var body = e.formInput.body;
GmailApp.setCurrentMessageAccessToken(e.messageMetadata.accessToken);
var draft = GmailApp.createDraft(recipient, subject, body);
// Return a built draft response. This causes Gmail to present a
// compose window to the user, pre-filled with the content specified
// above.
return CardService.newComposeActionResponseBuilder()
.setGmailDraft(draft).build();
}
On clicking the button, the addon crashes with the following error message: TypeError: Cannot read property "accessToken" from undefined.
e.messageMetadata seems to be undefined. Should I be looking for the access token somewhere else?
Simply removing the offending line
GmailApp.setCurrentMessageAccessToken(e.messageMetadata.accessToken);
doesn't work. The add-on crashes with a different error
Access denied: : Missing access token for authorization. Request: MailboxService.CreateDraft.
Update after comments:
This is the code for the button widget that triggers the compose action:
var submitButton = CardService.newTextButton()
.setTextButtonStyle(CardService.TextButtonStyle.FILLED)
.setText('Yes')
.setComposeAction(
CardService.newAction().setFunctionName('autofillEmailDraft'),
CardService.ComposedEmailType.STANDALONE_DRAFT
);
This is the logged 'e' object:
{
formInput={body=Hello},
parameters={},
draftMetadata={
toRecipients=[abcd@example.com],
bccRecipients=[],
ccRecipients=[]
}
}
