The buyer city is missing
The `Buyer city` element (BT-52) must be provided.
Only the issuer holds this value: Factlint reports it and never fabricates it. Test your invoice to find out whether it is affected.
The message your validator prints

Test your file with this error in mind
Upload the invoice involved: the report will say whether this code appears, where it appears in the document, and whether Factlint can only report it or also fix it.
To automate this check in an ERP flow, call the validation API and link every returned code to its public page.
Why this error happens
The mirror of BR-DE-3, on the buyer's side. It often fires alone: the seller's address comes from a setup done carefully once, the buyer's from a customer import whose completeness nobody checks.
How to fix it
Complete the customer record. The city does not follow from the post code.
