invalid_datasource_create_args

Error message

datasource-create requires dbType

What it means

CliDomainException code invalid_datasource_create_args from validateCreateRequest: dbType must be non-blank to create a datasource. dbType is required first because subsequent normalization and driver defaults depend on it.

Solutions

1. Set dbType to a supported value (e.g. MYSQL, POSTGRESQL, ORACLE) in the create request.
2. Validate the request payload shape before sending; dbType is mandatory.

Example fix

// before
create({ host, port, database, user, password, environmentId })

// after
create({ dbType: 'POSTGRESQL', host, port, database, user, password, environmentId })

if (StringUtils.isBlank(request.getDbType())) {
    throw new IllegalArgumentException("dbType is required to create a datasource");
}

public boolean hasDbType(CliDataSourceCreateRequest r) {
    return r != null && StringUtils.isNotBlank(r.getDbType());
}

try {
    cliDataSourceService.create(request);
} catch (CliDomainException e) {
    if ("invalid_datasource_create_args".equals(e.getCode())) {
        return badRequest(e.getMessage());
    }
    throw e;
}

When it happens

Trigger: POST datasource create without a dbType field (or blank), while other fields may be present.

Common situations: UI/automation that leaves dbType unset or sends an empty string; a malformed payload that dropped the type.
