${type} requires valid configuration

Error message

${type} requires valid configuration

What it means

AbstractAgentTypeProvider.validateDSL() performs baseline validation of an agent DSL definition map before generation. A null root map throws IllegalArgumentException('<agentType> requires valid configuration'); blank or missing 'name' fields throw related messages. Subclasses may extend this validation for agent-type-specific rules.

Solutions

1. Pass a non-null Map containing at least a non-blank 'name' field to validateDSL
2. Fix upstream parsing so an empty/failed DSL load surfaces an error instead of null
3. Check the agent definition file exists and parses to a YAML/JSON object (not empty)

Example fix

// before
Map<String,Object> root = yaml.load(in); // null if file empty
provider.validateDSL(root);
// after
Map<String,Object> root = yaml.load(in);
if (root == null) { throw new IllegalStateException("Agent DSL file is empty or invalid"); }
provider.validateDSL(root);

if (root == null || root.get("name") == null || root.get("name").toString().isBlank()) {
    throw new IllegalArgumentException("Agent DSL must be a non-null map with a 'name' field");
}

boolean isValidDsl(Map<String,Object> root) {
    return root != null && root.get("name") instanceof String s && !s.isBlank();
}

try {
    provider.validateDSL(root);
} catch (IllegalArgumentException e) {
    log.warn("Invalid agent DSL: {}", e.getMessage());
}

When it happens

Trigger: Calling validateDSL(Map) with null as root — typically when the agent definition failed to deserialize/parse upstream (empty YAML/JSON file, failed fetch) and null was propagated instead of an empty map.

Common situations: Loading an agent DSL from an empty or unreadable file, an API response that produced null instead of a map, calling providers programmatically without constructing the DSL map first.
