Strange error with Reports

[antoineL 0]

ERA Protect server 9.0.1144 on Windows 2016 with SQL server 2014 Express 12.0.6433, ERA.war 9.0.138 on Tomcat 9.0.63/Microsoft JDK 17.0.3, all on the same server. This setup works flawlessly for several months; but today I got strange failures.

When looking at many reports (not all), through dashboard or directly under Reports/, I got an alert "Failed to load data; 500 The call failed on the server: see server log for details." With the dashboard, I got as many alerts as there are report widgets, so I guess it is report-related.

I do not know which "server log" I should look at; I searched ERAserver, Tomcat, SQLserver and did not get anything which might correlate the problem.

However, I got another error (which is probably related) when I try to edit the report definition (slightly edited at the URL):

By the way, that one is with Chrome; but I got the same failure with almost the same message on Firefox 91.9.1; just Firefox adds a TypeError exception is raised since "this.H.c.G is null"
