Split a block in two. The head keeps its ID and links to the new block.
Usage
vf workflow split-block [flags]Examples
vf workflow split-block --workflow-id <id> --block-id <id> --project-id <id> --environment-alias <value> --at-step-id <id>Flags
--acknowledge-rewire Required when the step that becomes the last step has hidden links or actions. The split keeps them, so they start to run. An action list on its next exit is deleted, because next links to the new block.
--at-step-id string The step that starts the new block. It and every step below it move there, and the step above it becomes the last step of the block. To make step X the last step, so that its fail and path ports run, send the step below X. It must not be the first step. [required]
-b, --block-id string [required]
--body string Request body as JSON (alternative to individual flags). Can also be provided via stdin.
--environment-alias string [required]
--expected-steps stringArray The block's step IDs exactly as your last read returned them. If the block changed, nothing is written. [required]
-h, --help help for split-block
-n, --name string The new block name. Default: the block name with " (continued)".
-p, --project-id string [required]
-w, --workflow-id string [required]Global flags
