Confirm your documents extension

Did you get this error message when trying to create a signing session?

If yes, it is because you have a document without a valid extension in the name.

To resolve this situation, follow these steps:

Go to the folder’s EDM
Check the box to include the Masked Documents
Look for the document in the EDM not having an extension, or having a non-valid one in their name
Once you find it, click on the pencil
Add/Modify the extension to put a valid one; then click Save and close

Note:
If the document that does not have a valid extension is hidden, click on the icon with a cross to make it available for modification

After doing that, you should be able to create your signing session

You can find a list of accepted document extension in the adding document window

Here is the list:
