URGENT : BadGateway / GatewayTimeout during Merge PDF

For certain sets of documents, I’ve been encountering a GatewayTimeout error during the merge process.

The previous steps, where the documents are collected into an array, complete successfully. However, the merging step consistently fails with the GatewayTimeout error.

We are subscribed to the 75k document transaction pack, and we expect this process to run smoothly without disrupting our daily operations.
