Jira Behaviour Code is not Updating the Field Value?

[Felix Trauner]

Hi all,

I'm working on a Jira Behaviour using Scriptrunner, and I’m trying to set the value of a custom field based on an API response. The code runs without errors, and the condition is met (the custom field value is "Nein"), but the field doesn't get updated as expected. Below is the code I'm using:

async function main() {

    // Get the Parent Key from the field (e.g., Parent Issue)

    const parentField = getFieldById("parent").getValue();

    const parentKey = parentField.key;

    console.log('Parent Key:', parentKey);

    try {

        // Perform the API request

        const res = await makeRequest(`/rest/api/3/issue/${parentKey}`);

        // Check the response content

        const data = await res.body;

        console.log('Fetched Data:', data);

        // Check if the custom field has the value 'No'

        const parentAutomSupportValue = data.fields.customfield_10087.value;

        // Automatic support (e.g., set a value)

        if (parentAutomSupportValue === 'Nein') {

            getFieldById("customfield_10087").setValue('10085');

            getFieldById('customfield_10106').setRequired(true);

        }

    } catch (error) {

        console.error('Error during fetch:', error);

    }

}

// Call the main function

main();

I've confirmed the API call is working and the value of customfield_10087 is correctly being retrieved, but the field doesn't seem to update when I expect it to.

Can anyone explain why this might be happening or suggest a solution?
