I need to have dynamic:strict in my mapping because I have malformed JSON.
I need to ignore malformed fields for example: (first normal field and secondly malformed)
{
key1: value1
}
{
key which is 1: value1
}
"key which is 1" is a malformed field which occurs through dependencies and I cannot change it. It get's parsed because I parse k,v with '='
How can I ignore field: "key which is 1" in my index?
If I cannot simply ignore it, elasticsearch rejects the whole document. Which cannot happen. It should index document except this field.
I will be able to set the field before it is indexed because of "dynamic":"strict

Would you be able to send the bad JSON through an ingest node? If so, you can ignore the bad stuff via the [JSON processor](https://www.elastic.co/guide/en/elasticsearch/reference/master/json-processor.html).
