Error message

No code in target project: 

What it means

After permission checks, the TOD create-pull-request endpoint resolves targetBranch, defaulting to targetProject.getDefaultBranch(). If no branch was specified and the target project has no default branch (typically an empty repository), it throws a JAX-RS NotAcceptableException (HTTP 406) naming the project path.

Solutions

1. Explicitly pass a valid targetBranch that exists in the target project.
2. Push an initial commit to the target project so a default branch exists.
3. Set the project's default branch in project settings (branches section).

Example fix

// before
var data = new HashMap<String, Serializable>(); // no targetBranch
// after
data.put("targetBranch", "main"); // branch that exists in target project

String branch = targetBranch != null ? targetBranch : targetProject.getDefaultBranch();
if (branch == null || targetProject.getBranches().stream().noneMatch(b -> b.equals(branch)))
    throw new IllegalStateException("Target project has no usable branch");

try {
    callCreatePullRequest(params);
} catch (NotAcceptableException e) {
    if (e.getMessage().startsWith("No code in target project")) {
        // prompt user to pick/push a branch in the empty target
    } else throw e;
}

When it happens

Trigger: POST to create-pull-request with targetBranch omitted against a target project that is empty or has no default branch configured.

Common situations: Newly created project with no commits; default branch renamed/deleted so the setting is empty; targeting an empty fork parent.
