HelloSign gives 'Invalid custom field' error

Question

I am using a HelloSign template and passing data to it using HelloSign PHP SDK on a Symfony project.

I used the same API ID in the template to pass data to the template but I am getting 'Invalid custom field: b1_fullname' error.

Here's my code,

$client = new \HelloSign\Client('zzzzzzzzzzzzzzzzzzzz');
$hs_request = new \HelloSign\TemplateSignatureRequest;
$hs_request->enableTestMode();
$hs_request->setTemplateId('xxxxxxxxxxxxxxxxxx');
$hs_request->setTitle('Test');
$hs_request->setSubject('Test');
$hs_request->setMessage('Test');
$hs_request->setSigner('Client', 'aaa@bbb.com', 'AAA');
$hs_request->setCustomFieldValue('b1_fullname', 'AAA BBB');

$hs_response = $client->sendTemplateSignatureRequest($hs_request);

Here's how the template API field ID looks like.

When setting up the template, you'll need to set "Who fills this out?" to "Me (when sending)" so the API knows the expect a value for the custom field: Template Field Example
