Hello team,  
We've just upgraded our stack to version 7.6.0 using the official helm charts and when we open the JVMs dashboard in APM, we get the following errors:

"message":"TypeError: Cannot read property 'key' of undefined\n at getServiceNodeMetadata (/usr/share/kibana/x-pack/legacy/plugins/apm/server/lib/services/get\_service\_node\_metadata.js:57:171)\n at process.\_tickCallback (internal/process/next\_tick.js:68:7)"

"message":"Internal Server Error","name":"Error","stack":"Error: Internal Server Error\n at HapiResponseAdapter.toInternalError (/usr/share/kibana/src/core/server/http/router/response\_adapter.js:63:19)\n at Router.handle (/usr/share/kibana/src/core/server/http/router/router.js:165:34)\n at process.\_tickCallback (internal/process/next\_tick.js:68:7)"

Any idea? Thanks,  
Chen.

Hi there,

Thanks for trying out the new 7.6.0 release. The bug you ran into unfortunately made it into the release. A fix has already been implemented and will ship in 7.6.1 [https://github.com/elastic/kibana/pull/58481](https://github.com/elastic/kibana/pull/58481)
