{
"error": {
"root_cause": [
{
"type": "resource_already_exists_exception",
"reason": "index [logstash-2019.10.18/WkbT-3mxRkW1avQz-WFQKQ] already exists",
"index_uuid": "WkbT-3mxRkW1avQz-WFQKQ",
"index": "logstash-2019.10.18"
}
],
"type": "resource_already_exists_exception",
"reason": "index [logstash-2019.10.18/WkbT-3mxRkW1avQz-WFQKQ] already exists",
"index_uuid": "WkbT-3mxRkW1avQz-WFQKQ",
"index": "logstash-2019.10.18"
},
"status": 400
}

doing this:

PUT logstash-2019.10.18
{
"mappings": {
"properties": {
"namex": {
"type": "geo_point"
}
}
}
}
