Include content with replacement macro doesn't work

[Former user]

The macro doesn't work at all, just shows the "Macro execution error: Null" message, but there is nothing in the atlassian-confluence.log This error persist in 6.15.7 and 7.4.6.

I'm unable to reproduce the error.

This macro haven't work more than 3 years.

Currently we use the 7.19.x Confluence version with plugin version 2.6.0, but since 2021, this feature doesn’t work anymore….
