Issue

When attempting to generate a document using the PDF Document Generation module, the following error is thrown that prevents the document creation process:

DOCGEN_RUNTIME_ERROR: Failed to send result back: Request body larger than maxBodyLength limit.

Environment

PDF Document Generation

Cause

The PDF Document Generation module has the following limitation, and it's not possible to increase the maxBodyLegnth value.

• The maximum file size is 25 MB per document. If the document exceeds this limit, the action will result in an exception. 

Solution/Workaround

• If the document exceeds this limit(25 MB per document), it is recommended to compress high-resolution images to reduce the file size.
• An alternative is to generate the PDF in separate parts (separate PDFs) and then combine the PDFs using the PDF merge actions from the Community Commons module.
