I'm getting an OLE "unspecified error" on this line from the testing code below. Happens after about 10 seconds. Any way to know why it's not working?

lcXML = oRequest.submitRealtimeRequest(TextRequestMessage)

Code block:

TextRequestMessage = ;
	"ISA*00*          *00*          *ZZ*123456         *ZZ*MCKESSON_TSH   *031013*" + ;
	"1636*U*00401*000000001*0*T*:~GS*HS*123456CM*MMOSCC*20031013*1636*000000001*X*" + ;
