@rjler Thanks for raising this, we will investigate. In the meantime in order to unblock you, could you try using build:example:master to install the latest Open MCT and see if the quickstart example works for you?

Thanks again. Let us know if you run into any other issues.

@rjler this is a bug with our optional dependency checks. I have opened a PR to fix this

[rjler]

Thanks for help ...

npm run build:example:master Fixed the initial issue but encountered 'missing taxonomy'

From the developer tools:

Modified example/index.js ( changed localhost: to host ip ):

Working as expected:

@rjler can you try using 0.0.0.0 instead of your host IP? It looks like there's a CORS issue

Modified example/index.js

const config = { "yamcsDictionaryEndpoint": "http://0.0.0.0:9000/yamcs-proxy/", "yamcsHistoricalEndpoint": "http://0.0.0.0:9000/yamcs-proxy/", "yamcsWebsocketEndpoint": "ws://0.0.0.0:9000/yamcs-proxy-ws/", "yamcsUserEndpoint": "http://0.0.0.0:9000/yamcs-proxy/api/user/", "yamcsInstance": "myproject", "yamcsProcessor": "realtime", "yamcsFolder": "myproject", "throttleRate": 1000, "maxBatchSize": 15 };

Get missing:taxonomy

From dev tools:

Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at http://0.0.0.0:9000/yamcs-proxy/api/user/. (Reason: CORS request did not succeed). Status code: (null).

@rjler how are you running yamcs? are you using the provided Makefile in quickstart to spin everything up via docker?

[rjler]

quickstart: From https://github.com/akhenry/openmct-yamcs?tab=readme-ov-file#prerequisites followed the quickstart link to: https://github.com/yamcs/quickstart. The followed the instructions. No docker involved, executing YAMCS quickstart and openMCT on the same Ubuntu host. Using Firefox, on a Mac, on the same network ( 192.168.0.xxx ) to access openMCT ( 192.168.0.69:9000 ).

@rjler Thanks for the info. Seems like the non-docker workflow has broken due to some recent change-- will investigate. In the meantime, you may try the docker workflow and see if that fits your needs.
