Issue Summary

If a space has pages with Lucidchart diagrams, and this space is relatively large, taking more than 5 minutes to be exported to PDF, the export may fail.

Steps to Reproduce

1. Create a complex space with high quantity of pages
2. Create a few pages with Lucidchart diagrams (in different positions on the page tree)
3. Try to export the entire space to PDF

Expected Results

The space should be exported without problems

Actual Results

If the export takes more than 5 minutes, it may fail.

Notes

This happens because the token for the temporary lucid-chart image only lasts 5 minutes, causing a 403 http status if the conversion to PDF tries to access that image after that period:

Workaround

Either:

• Select less pages to be exported, decreasing the export time

OR

• Don't select the pages containing Lucid-chart diagrams

OR

• Export the space to HTML, as the problem shouldn't affect it
