I'm getting this error in few other places, I'm trying to move my independent core component & create one of my core component as a library. all this code within the original project

export const workFlowDefinitionsControllerApi = function(val: string) {
  return axios.get(`${base_url}/api/v1/workflow/config/definition?workflowKey=${val}`, header);
};
