After creating a Data Loading Form, events are stuck in "Pending" status. Using the "Load Pending Records" option is not effective - the records remain stuck.
In the t_log table, there is an error of the following form:
error : "Name" attribute in "AdapterConfiguration/InputFormatCollection/InputFormat/InputFormatFields/InputFormatField" node is empty or contains illegal characters ("SLA Applicability"). Legal characters are A-Z, a-z, 0-9 and _ .
As per the error message, the input field names for Data Mapping cannot contain spaces, only alphanumerics and underscore. Correcting this allows the form to work.
