reference-cycle

All codes

• Type: error
• Kind: input (the input is malformed beyond what tolerance repairs)

What happened

A reference chain or the page tree loops back on itself.

Why

Damaged or hostile files.

How to fix

Use another copy of the file.

Example

5 0 obj 6 0 R endobj
6 0 obj 5 0 R endobj

Resolving object 5 leads back to itself; the call fails instead of looping. A page tree whose /Kids lead back to an ancestor fails the same way.

Data fields

None.
