The n8n LinkedIn node (n8n-nodes-base.linkedIn v1) is hardcoded to use LinkedIn API version 20250401 which does not exist, causing all LinkedIn posting operations to fail with error code NONEXISTENT_VERSION.

Hi @G_L_Lokesh Welcome!
LinkedIn retires each API version after a year and the node carried that value in its own code, so every post request returns 426 once it expires. It was corrected in n8n 2.18.0 and backported to 2.17.3, so updating clears it. Current stable is 2.29.8. On npm:

npm update -g n8n

On Cloud, pick a newer version from the version dropdown in your workspace settings.
