Using api trying to attach node in cluster in platform9

Hi Team,

Using api, I am trying to attach node in pf9 cluster.
Below curl command returns status ‘ok’ while its failing to attach node.
Attached pf9 cluster log for reference.Processing: platform9_cluster.log…

curl -k -X POST ‘https://pmkft-1632505444-98123.platform9.io/qbert/v3/17a6222596e24e348a82a14f241e321/clusters/1ee486fb-13a5-4bbf-88ad-001c3434df6d/attach’ -H ‘x-auth-token: gAAAAABhcT3lNSUlt3lFYNUnZ_SiDy0PGNwbWrj_RNT3xg46ni0Ce_kKdTN-byhhkoGf8VYZ9cc-gXdi_0yjnJfyXI9I23mRoegRVCsIPWtFyde99prH60fTu1YQv-zougCUk2gf0ryegCEY_n-8l05oRbfJX2603SWPfh2Bf5V2O5m7JZGkSWYOgL8DDsu-2IGG3Yauj6Rn’ -H ‘Content-Type: application/json’ -d ‘[

@Deepak have you run the CLI to Prep Node?
The CLI can also be used to Attach a node to an existing cluster?

We have achieved this using api. Thanks for your reply.
