		{
			"severity": "error",
			"code": "processing",
			"diagnostics": "HAPI-2409: org.hl7.fhir.r4.fhirpath.FHIRLexer$FHIRLexerException: Error @1, 8: Unterminated string"

	]
}

The request is completed normally on hapi-fhir verrsion 8.2.0.

Additional Info:
If we remove the dot from the url then the request is completed for eg.
From:

   {
     "name": "path",
     "valueString": "Task.businessStatus.coding.where(system='http://customurl.com/fhir/CodeSystem/order-businessStatus')"
   }

To:

   {
     "name": "path",
     "valueString": "Task.businessStatus.coding.where(system='http://customurlcom/fhir/CodeSystem/order-businessStatus')"
   }

The issue remains same for normal string. For eg:
Error: hapi.fhir
No Error: hapifhir
