Getting invalid JSON, despite JSON being valid when manually hard-code the output of the expression

Hi

If the Value is taken from the node field value I get an error message saying “invalid JSON in response code”
If I manually type in the value I get success.
If I try other fields, some work, some don’t.

Fails when using Node Value:

Success when manually typing in value:

Interestingly, it works if I use {{ $(‘Zoho CRM SQL effective>/status_is_null&product_is_null’).item.json.data[0].supplier_sku }}

I tried to copy the scenario but it includes token and company information - if needed, please advise how to copy and paste without sensitive data.

Migrating my first flow from Make.com and got stuck.

Thanks in advance
