Thanks for the answers, the fact is that it does generate the pdf, but not with the data that does appear in the preview, it is as if in the invoice, it could not take the data that does appear in the configuration and is seen in the preview pdf.
And now, have this:

OwlError: Invalid prop suffix

Hey,

There can be an issue of wkhtmltopdf version you should match it with the appropriate version's requirement.txt version.
Also you can check one more thing first : the report.url should be set to http://localhost:8069.

Hi,

Try like following

You can add a template for the company details and call that from your report template

<template id="report_session">
            <t t-call="report.html_container">
                <t t-foreach="docs" t-as="doc">
                    <t t-call="report.external_layout">
                    </t>
                </t>
            </t>
</template>

In reports/views/layouts.xml:

<template id="external_layout">
    <!-- Multicompany -->
    <t t-if="o and 'company_id' in o">
 <t t-set="company" t-value="o.company_id"></t>
    </t>
    <t t-if="not o or not 'company_id' in o">
        <t t-set="company" t-value="res_company"></t>
    </t>

    <t t-call="report.external_layout_header" />
    <t t-raw="0" />
<t t-call="report.external_layout_footer" />
</template>
