Looks like a localisation issue. Your floats are formatted as "6,6584e+01", whereas the JSON decoder expects "6.6584e+01".
Can you run the following few lines please? Then I'll be able to write a test using the same setup as you:

This should be fixed in the latest commit to the midas develop branch. The JSON specification requires a dot for the decimal separator, so we must ignore |

Thanks for the bug report Gennaro!
I've fixed the code so that we'll now find the end-of-run ODB dump even if the user is already at the end of the file when they call get_eor_odb_dump().

 22 Jan 2024, Ben Smith, Bug Report, Warnings about ODB keys that haven't been touched for 10+ years
|
We have an experiment that's been running for a long time and has some ODB keys that haven't been touched in ages. Mostly related to features that we don't
use like the elog and lazylogger, or things that don't change often (like the logger data directory).

First the general advice: if you reduce the "period" of your equipment, then your function will get called more frequently. You can set it to 0 and we'll |

The ALPHA experiment at CERN has recently adopted MIDAS, and the history data in numerical form is needed by the collaboration. Furthermore the DAQ is running
under linux and most collaborators are windows or mac users, so it should be available in a platform independent way.

08 Aug 2019, Art Olin, Suggestion, midas cmake migration
|
I want to report a bug in the ROOT build process that might be relevant to the midas implementation. I had an annoying failure to build root 6.18 (current
pro version) with a misleading error message about a fault in the root code. It turned out this was a cmake problem, and the error was from my cmake version
being older than 3.14, which is quite recent. Took a bit of searching to find this.
