Hi Elastic Team,
I am running Multiple O365 Tenants in filebeat
but some of the tenants giving following warning
```auto
Got error 500 The input stream is not a valid binary format. The starting contents (in bytes) are: 22-68-74-74-70-73-3A-5C-2F-5C-2F-6F-33-36-35-61-64 ...: api error:(none) (none)
```
This is causing data loss in those tenants
Please help regarding this
Thanks !
