Try to use node-opcua-client (npm) with Deno but struggle

Hello, I want to try to migrate a little app to Deno because the compile option suit my need and that now it support npm package. I want to use the npm package node-opcua-client but I've got this error message

error: Uncaught (in promise) DataError: 'key_ops' property of JsonWebKey is invalid

NodeOPCUA creates automatically a default certificate when a client is first started. But my guess is either the symlink deno create for node_modules cause the issues or a permission missing but I already run the project using -A. I don't have this with Node Can you help me troubleshooting this ?

That seems like an internal bug in Deno. I would appreciate if you could open an issue in Github with reproeuction
