Certain cards and inputs in Okta Workflows will only accept specific data types.

It may not be possible to save the flow if the input is invalid - Invalid type conversion. Here's an example of what that might look like:

Save Failure
Your flow can't be saved because it is invalid.
Correct the problems and try again.

NOTE:

• The red text in the label of the To field of the O365 Send Email card indicates an issue with that input.
• Red labels in the flow are a good indication of where the problem with the configuration might be.

• O365 Mail - Send Email action
• Gmail - Send Email action
• Okta Identity Engine (OIE)
• Okta Classic Engine

The To and CC fields of both the Gmail and O365 Send Email cards accept a List of text values.

It is possible to drag a text value into these inputs, even though they accept a List.

To create a suitable input for the Gmail or O365 Send Email cards, use the following steps:

1. Add a List - Construct card.
2. Drag or type the e-mail addresses into the List - Construct card created in Step 1. 
3. Set the input types to Text.
4. Set the output type of the List - Construct to a list of Text.
5. Now should be possible to drag the list of recipients from the output of the List - Construct card into the To, CC, or BCC fields of the O365 and/or Gmail - Send Email cards.
