Prometheus with sub websocket

[Irupt]

Hello, when I activate the subscription with WebSocket, the Prometheus plugin crashes. I get this error message :

Internal error occurred during message handling. Please check your implementation. TypeError: Cannot read properties of undefined (reading 'operationName') 2025-01-14 15:40:15 at /usr/app/node_modules/@graphql-yoga/plugin-prometheus/cjs/index.js:82:98 2025-01-14 15:40:15 at /usr/app/node_modules/@envelop/core/cjs/orchestrator.js:114:17 2025-01-14 15:40:15 at onSubscribe (/usr/app/dist/apps/gateway/main.js:411:31) 2025-01-14 15:40:15 at processTicksAndRejections (node:internal/process/task_queues:95:5) 2025-01-14 15:40:15 at onMessage (/usr/app/node_modules/graphql-ws/lib/server.js:149:59) 2025-01-14 15:40:15 at WebSocket.<anonymous> (/usr/app/node_modules/graphql-ws/lib/use/ws.js:83:21)

By looking at the code, I found that context.params could be undefined during subscription operations.
