Why do I receive the message "Uploaded file should contain at least one value tag" when attempting to upload a masking XML configuration file in myLiveLOOK account?

Environment:

Cobrowse

Resolution:

The message "Uploaded file should contain at least one value tag" is generated when attempting to upload a masking configuration XML file where the first line in the file is an XML comment designated by an opening <? and closing ?>.

An example of an common XML comment seen in these files is <?xml version="1.0" encoding="UTF-16"?>. 

To resolve the issue, remove the XML comment line, save the file, and upload it once more.

Notes:

If the masking file has been copied or downloaded from a source where the "-" symbols precedes any of the <tags>, these will also need to be removed before saving and uploading the XML file.

For example, the following was copied from a masking file opened from within myLiveLOOK.  The highlighted texts need to be removed before attempting to upload XML file again:

<?xml version="1.0" encoding="UTF-16"?>
