Index Lifecycle Error- Check rollover ready

After I ran these queries, my filebeat index isn't collecting data on discover and gives me following error-

PUT filebeat-7.4.0-2019.11.08-000001/_settings
    {
    "index": {
    "blocks": {
    "read_only_allow_delete": "false"
    }
    }
}
    
    POST /filebeat-7.4.0-2019.11.08-000001/_shrink/filebeat-7.4.0-2019.11.18-000001
{
  "settings": {
    "index.routing.allocation.require._name": null, 
    "index.blocks.write": true
  }
}

Error-

Index lifecycle error
cluster_block_exception: index [filebeat-7.4.0-2019.11.08-000001] blocked by: [FORBIDDEN/12/index read-only / allow delete (api)];

The error also says, Current Action: rollover and Failed Step: check-rollover-ready. Please help how to undo this.
