When I try to refresh fields in index-pattern, I get a "Payload Too Large" error message:
What can I do to avoid this type of error?
This is related to the limit of fields in the index, i.e. there are too many fields. These limits can theoretically be increased, but this has a negative impact on the indexing rate in the entire cluster so I would definitely advise against it. I would suggest reducing the number of fields or dividing the pattern into several smaller ones.
