Scripted field to count occurence in string does not work

Elastic Stack Elasticsearch

Hi, I am trying to create a scripted field on Kibana for counting the number occurrences of slash ('/') character inside a string field like so:
doc['my_field.keyword']?.value?.count('/')
But 'discover' page throws me 'Courier Fetch: 5 of 15 shards failed.' and is not able to show any data (No result found).

I have another scripted field that is just for counting the length of that same field like so:
doc['my_field.keyword']?.value?.length()
And it works fine. Which means there is nothing wrong with that field but perhaps the 'count' method is not supported in scripted field?

There is no such thing as a count method. You need to implement this count using your own algorithm.

Painless is limited to what Java can provide in terms of API.
