Hello,
i used the get multiple tasks endpoint a couple of times successfully already.
But today i found a strange behaviour where it would return bad request for a project where i am in?
is use the following parameters to filter by a project and return name and custom_fields
'project' => PROJECT_ID, 'opt_fields' => 'custom_fields,name'
this worked great for others projects but i cant find the difference why this one project return bad request
