Hi,


This error usually happens when the QWeb template tries to access the currency symbol using env.company.currency_id.symbol, but currency_id is missing or not properly loaded.



Solution


1- Ensure the currency symbol is properly added in the company.


2- Try with the code.


* Use 'request.env' for safer access in QWeb

<xpath expr="//th[contains(., 'Balance') and span[contains(@t-out, 'currency_id')]]" position="replace">
<th class="text-end">Balance <span t-out="request.env.company.currency_id.symbol"/></th>
</xpath>

OR


Add a condition to prevent template crash

<xpath expr="//th[contains(., 'Balance') and span[contains(@t-out, 'currency_id')]]" position="replace">
<t t-if="env.company.currency_id.symbol">
<th class="text-end">Balance <span t-out="env.company.currency_id.symbol"/></th>
</t>
</xpath>

Hope it helps
