Briefly, this error occurs when Elasticsearch attempts to delete data from a repository that has been set to read-only. This could be due to incorrect permissions or a misconfiguration. To resolve this issue, you can either change the repository’s permissions to allow write operations or ensure that no delete operations are being attempted on the read-only repository. Additionally, check your Elasticsearch configuration to ensure it’s not mistakenly set to treat the repository as read-only.
