Error message with unexpected format: '[\d]+ b'

On rare occasions (2 instances within the past 90 days), when using the purgeExternalElements method in v-connection, we received the following error:

Error: PepTalk unspecified error for request 29374: Error message with unexpected format: '29374 b' at PepTalk.processMessage (/opt/node_modules/@tv2media/v-connection/dist/peptalk.js:217:21) at PepTalk.processChunk (/opt/node_modules/@tv2media/v-connection/dist/peptalk.js:149:26) at WebSocket.emit (node:events:513:28) at Receiver.receiverOnMessage (/opt/node_modules/ws/lib/websocket.js:1068:20) at Receiver.emit (node:events:513:28) at Receiver.dataMessage (/opt/node_modules/ws/lib/receiver.js:517:14)

I expect that the 29374 is just the request identifier.
