Waiting for @jirapongse.phuriphanvichai to verify a problem that was found by the customer.
I've checked the case already. There is no further information, so I'll extend its triage to next week.

This appears to be expected behavior from the ADS when a WebSocket App Posts data with the key primitive type of Buffer. The workaround is using AsciiString as the key primitive type. With this type, the data was properly consumed/displayed by both WebSocket and RSSL consumers.
def send_symbol_list_post(ws):
global post_id
sl_post_json = {
'ID': 1,
'Type':'Post',
'Domain':'SymbolList',
'Key':{
'Name': "SYM"
},
'Ack':True,
'PostID':post_id,
'PostUserInfo': {
'Address':position, # Use IP address as the Post User Address.
'UserID':os.getpid() # Use process ID as the Post User Id.
},
'Message': {
'ID': 257,
'Type':'Refresh',
'Domain':'SymbolList',
'Key':{
'Name': "SYM",
'NameType': "Ric"
},
'Solicited': False,
'Complete' : True,
'ClearCache' : True,
'State':{
'Stream': 'Open',
'Data': 'Ok',
'Code' : 'None'
},
"Map":{
"Entries":[
{
"Action":"Add",
"Key":"RIC1"
},{
"Action":"Add",
"Key":"RIC2"
},
{
"Action":"Add",
"Key":"RIC3"
}
],
"KeyType":"AsciiString",
}
}
}
ws.send(json.dumps(sl_post_json))
print("SENT:")
print(json.dumps(sl_post_json, sort_keys=True, indent=2, separators=(',', ':')))
post_id += 1

Yes, I can use off-stream posting to post SymbolList to cache in ADS. You need to have a service that can accept post. The following is code in Python.
def send_symbol_list_post(ws):
global post_id
sl_post_json = {
'ID': 1,
'Type':'Post',
'Domain':'SymbolList',
'Key':{
'Name': "SYM"
},
'Ack':True,
'PostID':post_id,
'PostUserInfo': {
'Address':position, # Use IP address as the Post User Address.
'UserID':os.getpid() # Use process ID as the Post User Id.
},
'Message': {
'ID': 257,
'Type':'Refresh',
'Domain':'SymbolList',
'Key':{
'Name': "SYM",
'NameType': "Ric"
},
'Solicited': False,
'Complete' : True,
'ClearCache' : True,
'State':{
'Stream': 'Open',
'Data': 'Ok',
'Code' : 'None'
},
"Map":{
"Entries":[
{
"Action":"Add",
"Key":"RIC1"
},{
"Action":"Add",
"Key":"RIC2"
},
{
"Action":"Add",
"Key":"RIC3"
}
],
"KeyType":"Buffer",
}
}
}
ws.send(json.dumps(sl_post_json))
print("SENT:")
print(json.dumps(sl_post_json, sort_keys=True, indent=2, separators=(',', ':')))
post_id += 1

Thank you very much for sharing the idea. The data was posted. But when I consume the symbollist, seeing "D" for Name instead of "RIC1" (Xwindow) and other chars on putty. What am I missing?
I got the same issue when subscribing with RSSL 14002. I work fine with WebSocket API.
I will verify the problem.
