REUSE status suddenly shown as non-compliant

[daogrady]

Hi,

reuse marked one of our projects as non-compliant today. The error is rather nondescript:

A violation against the OSS Rules of Play has been detected.

Rule ID: rl-reuse_tool-4
Explanation: Is it compliant with REUSE rules? No

Find more information at: https://sap.github.io/fosstars-rating-core/oss_rules_of_play_rating.html

Running reuse lint locally shows the project is still compliant:

# SUMMARY

* Bad licenses: 0
* Deprecated licenses: 0
* Licenses without file extension: 0
* Missing licenses: 0
* Unused licenses: 0
* Used licenses: Apache-2.0
* Read errors: 0
* Files with copyright information: 146 / 146
* Files with license information: 146 / 146

Congratulations! Your project is compliant with version 3.3 of the REUSE Specification :-)

This seems to have been an issue in the past:

#622
#424
#396

So maybe it's a false positive.

Best,
Daniel
