Briefly, this error occurs when the length of the UUID (Universally Unique Identifier) exceeds the size of the transaction log (translog) in Elasticsearch. The translog records changes made to Elasticsearch, and its size is limited. To resolve this issue, you can either reduce the length of the UUID or increase the size of the translog. However, increasing the translog size may impact performance, so it’s recommended to optimize the UUID length. Also, ensure that the UUID is correctly generated and doesn’t contain unnecessary characters.

 throw new TranslogCorruptedException(path.toString(); "UUID length can't be larger than the translog");
 }
 if (uuidLen <= 0) {
 throw new TranslogCorruptedException(path.toString(); "UUID length must be positive");
 }
 final BytesRef uuid = new BytesRef(uuidLen);
