+[IMPORTANT]
+====
+*Known Issue:* APM Server introduced support for cloud metadata in v7.9 ({pull}3729[3729]).
+Unfortunately, the JSON Schema was too strict, and does not account for `null` values.
+As a result, sending `null` values for cloud metadata causes the payload to be rejected.
+This issue was resolved in v7.10.0 ({pull}4142[4142]).
+To avoid problems, we recommend updating to version ≥7.10.0.
