I am working on odoo version 15; trying to customize receipt in POS module; but I have an internal server error (500).. My code as following:

manifest .py

...
'assets': {
        'web.assets_qweb': [
            'static/src/xml/OrderReceipt.xml',
            # 'views/OrderReceipt.xml',

        <t t-jquery=".pos-receipt .pos-receipt-contact" t-operation='append'>
            <t t-if='receipt.client'>
                <div style="font-weight:bold;">Customer:<t t-esc='receipt.client'/></div>

Try this and also add the error from logs in the questions add point_of_sale in manifest.py file in depends column And also, check if the client field exists

    <t t-inherit="point_of_sale.OrderReceipt" t-inherit-mode="extension" owl="1">

        <xpath expr="//div[hasclass('pos-receipt-contact')]" position="after">
            <t t-if='receipt.client'>
                <div style="font-weight:bold;">Customer:<t t-esc='receipt.client'/></div>
            </t>
            <p>Success !</p>
        </xpath>
