The log lines generated when MongoDB 4.4.x starts a windows service or removes it have issues with the strings included ("toUtf8String_serviceName").
For example:
{"t":{"$date":"2020-12-17T16:12:57.631+00:00"},"s":"I", "c":"CONTROL", "id":23316, "ctx":"main","msg":"Trying to start Windows service '{toUtf8String_serviceName}'","attr":{"toUtf8String_serviceName":"MongoDB"}}
or:
{"t":{"$date":"2021-03-26T05:32:09.899+00:00"},"s":"I", "c":"CONTROL", "id":23307, "ctx":"main","msg":"Trying to remove Windows service '{toUtf8String_serviceName}'","attr":{"toUtf8String_serviceName":"MongoDB"}} {"t":{"$date":"2021-03-26T05:32:09.900+00:00"},"s":"I", "c":"CONTROL", "id":23309, "ctx":"main","msg":"Could not find a service named '{toUtf8String_serviceName}' to remove","attr":{"toUtf8String_serviceName":"MongoDB"}}
Please review what's causing this.
