/check_mk/api/1.0/objects/agent/3c8d1a7ee35e1e01?host_name=<my hostname>&os_type=linux_rpm throws a HTTP 500 error

[MasopustC (Christian Masopust)]

Trying to download an agent with the API (tested with the interactive GUI and with the examples provided at the API documentation) result in the following error:

{
  "title": "Internal Server Error",
  "status": 500,

Any hint what’s wrong here?

This looks like the same issue I have:
Use REST API for automatic agent deployment - Troubleshooting - Checkmk Community

If I’m not mistaken, it should be fixed in 2.0.0p12: RESTAPI: fix agent information and agent download (checkmk.com)
Now we only have to wait until it is released

Hi @Wummeke and @MasopustC , p12 is now out

[MasopustC (Christian Masopust)]

already downloaded … but looks like your webserver certificate has expired (at least my wget complained about it )

[MasopustC (Christian Masopust)]

Can confirm that on my site this error has been gone!

Thanks a lot for your effort!

Downloading the agent works for me too, with this new release.
