Requesterror 400, 'search_phase_execution_exception', 'failed to parse date field Django

Question

I’m having trouble executing the views that receive an Elasticsearch, searches between dates coming from the template and returns a csv!

views:

...
data_inicio_template = request.POST.get('data_inicio')
data_fim_template = request.POST.get('data_fim')

data_inicio = datetime.strptime(data_inicio_template, '%Y/%m/%d %H:%M')
data_fim = datetime.strptime(data_fim_template, '%Y/%m/%d %H:%M')

body={"query":{"bool":{"filter":[{"range":{"data_importacao_rnds":{"gte":data_inicio,"lte":data_fim}}}]}}}
results = elasticsearch.helpers.scan(es, query=body, index=index)
df = pd.DataFrame.from_dict([document['_source'] for document in results])

response = HttpResponse(content_type='text/csv')

response['Content-Disposition'] = 'attachment; filename=dados'

df.to_csv(response, index = False)

return response

Error in that line: df = pd.DataFrame.from_dict([document['_source'] for document in results])

HTML:

<input id="datetimepicker" type="text" class="form-control form-control-sm" name="data_inicio" required>
<input id="datetimepicker2" type="text" class="form-control form-control-sm" name="data_fim" required>
<script>
$(function () {
  $("#datetimepicker").datetimepicker();
});
$(function () {
  $("#datetimepicker2").datetimepicker();
});

Ex.A survey between 20 and 21 May 2021, returns:

Requesterror(400, 'search_phase_execution_exception', 'failed to parse date field [2021-05-20T11:23:00] with format [[yyyy-MM-dd HH:mm:ss]]: [failed to parse date field [2021-05-20T11:23:00] with format [[yyyy-MM-dd HH:mm:ss:ss]]]')
