Undefined `actions` property in `/api/~node/services?withActions=true` causes empty REST API page

[ggondim]

I have had this bug with the "REST API" page for some time.

Symptoms

• The "REST API" page is blank:

• Services and actions are accessible via Moleculer Runner:

• Manually calling /api/~node/services?withActions=true does not return any actions:

Debugging

Upon delving deep into the problem, I discovered:

• An uncaught error in view's getServiceActions(svc.actions) due to an undefined actions property:

• Applying a console.log to the file moleculer/src/internals.js:L61 shows the withActions parameter as false, even when it's explicitly passed in the request:

• Additionally, applying a console.log to the file moleculer/src/registry/service-catalog.js:L117 shows an unrecognized parameter value, as L119 is never reached:

Help

• Is this correct? Am I missing something?
• Should there be improved error handling?
• How can I assist in rectifying this if it's indeed an error?

I discovered that mergeParams: false was the cause of this issue.

Developers should continue to use this configuration without experiencing side effects in internal services.

I implemented a minor workaround in src/index.js:L455 to force parameter merging for internal services, and it resolved the issue.
