the API. The error is still thrown. <o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">The error is thrown for a variety of users, the only thing they might have in common is an empty field ("EndDate") that is also read from the endpoint during import, but is already declared as a string, not a number.<o:p></o:p></span></p>
