Webhook doesn't receive files anymore

[Martijn3293]

Since today, our n8n flow no longer works.
From an application, we send an Excel file to a webhook in n8n. Here we suddenly keep getting the error message “Cannot set properties of undefined (setting ‘file’)”. We did not get this message last weeks.
Specifically: when sending multipart form data to the webhook, the webhook exactly does not receive the file.

In the meantime, we have seen a n8n update around processing traffic jams etc.
We have been able to restore n8n back to a release from back in November where it does work, but we cannot keep this version as it requires new nodes that did not yet exist in this old version.

• **n8n version:**1.12.1
• **Database (default: SQLite):**SQLite
• **n8n EXECUTIONS_PROCESS setting (default: own, main):**main
• **Running n8n via (Docker, npm, n8n cloud, desktop app):**Elestrio
• **Operating system:**macOS
