@mistic do you have any idea where this error is coming from? {"type":"stream_constraints_exception","reason":"String length (5046272) exceeds the maximum length (5000000)"}} at Array.map (<anonymous>)

[mistic]

@tsullivan I don't unfortunately. But it looks like a gigantic string being passed over an array map. Maybe from some data fixture from the tests itself?

Looks related to elastic/elasticsearch#96031
