Unable to fetch workflow_transistions for active workflow

async function get_workflow_transitions(frm) {
    console.log('Getting get_workflow_transitions--');

    // Check if frm.doc is defined and log it
    if (!frm || !frm.doc) {
        console.error('frm or frm.doc is not defined');
        return Promise.reject(new Error('frm or frm.doc is not defined'));
    } else {
        console.log('frm.doc:', frm.doc);
    }

    try {
        // Get the active workflow for the doctype
        let workflow = await get_active_workflow_for_doctype(frm.doc.doctype);
        console.log('Active workflow for doctype:', workflow);

        // Ensure the workflow object has the necessary properties
        if (!workflow || !workflow.name) {
            console.error('Invalid workflow object:', workflow);
            return Promise.reject(new Error('Invalid workflow object'));
        }

        return new Promise((resolve, reject) => {

            frappe.call({
                method: 'frappe.model.workflow.get_transitions',
                args: {
                    doc: frm.doc,            // The document

                    raise_exception: true,    // Raise exception if no transitions found
                },
                callback: function(response) {
                    console.log('Inside callback--');
                    if (response.message) {
                        console.log('Transitions FOUND--', response.message);
                        resolve(response.message);

                        reject(new Error(No transitions found for workflow ${workflow.name}));
                    }
                },
                error: function(error) {
                    console.error('Error calling frappe.model.workflow.get_transitions:', error);
                    reject(error);

    } catch (error) {
        console.error('Error getting active workflow:', error);
        return Promise.reject(error);
    }
}

Console logs-

giving Transitions FOUND-- []
transitions determine_workflow_action are-- []
 No workflow action found for the current state and conditions

but in “tabWorkflow Transition” it has transitions

is there anything I am missing?

have tried with workflow object in parameter workflow but getting error -

AttributeError: ‘str’ object has no attribute ‘workflow_state_field’
