Pinging @elastic/ml-core (Team:ML)

Seems to happen frequently, ~14%, backporting to 8.x until we can figure it out

Actually the fix is faster - #113456
🤦

[elasticsearchmachine]

This issue is being re-opened because the referenced test still exists in muted-tests.yml, so it is still muted.

Please check and unmute the test if it can be unmuted.

In the future, automation will automatically re-open issues whenever they are closed without unmuting the test first.

Reach out in #es-delivery or tag the delivery team if you have an issue.

It seems to me that the problem is that the string expected is GKNETXİTKF which contains the latin capital I with dot above character, where as the actual string is GKNETXITKF, which doesn't have the dot above. Possibly this is being converted to lowercase and then uppercase?

the random string generator is generating UTF16 strings - the REST controller decodes them as UTF8, which seems to convert İ to i. I couldn't seem to get the string generator to generate UTF8 strings (while excluding control messages, which the REST control is throwing errors on)

Reopening because it's still muted in 8.x
