Not eligible for multi-value

Error message

Not eligible for multi-value

What it means

SecretInput.convertToObject converts a single-element string list into the secret's String value. Because a secret input holds exactly one value (or none), a list with more than one element triggers 'Not eligible for multi-value'.

Solutions

1. Pass a list with at most one secret value string.
2. If multiple secrets are needed, define multiple separate secret inputs instead of one.
3. Inspect the source of the value list (UI binding or script) and ensure only one value is produced.

Example fix

// before
Object value = SecretInput.convertToObject(Lists.newArrayList("token1", "token2"));

// after
Object value = SecretInput.convertToObject(Lists.newArrayList("token1"));

boolean validSecretInput(List<String> strings) {
    return strings == null || strings.size() <= 1;
}

try {
    Object secret = SecretInput.convertToObject(values);
} catch (ValidationException e) {
    // secret inputs hold at most one value
}

When it happens

Trigger: Calling SecretInput.convertToObject(List<String>) with a list containing two or more strings, e.g. a job/buildspec input bound to a secret that receives multiple values.

Common situations: Automation or a script passing several secret values or a joined/quoted list into a single secret input; form/UI changes sending multiple selections where the input is single-valued; misconfigured buildspec copy-pasted from a multi-value input.

Understand the failure class

Background: "Must be a positive integer", "Invalid value", "Unsupported": the invalid-argument-value error family, when a library rejects the value you pass — this error's family across 35 libraries.
