FT0 and FV0 digit reader error, missing digitizer configuration

O²
1

Dear Experts,

I run with a just-updated QC and O2. I try to run the following:

o2-fv0-digit-reader-workflow --fv0-digit-infile <some_rootfiles> | o2-qc --config json://<some json file> -b

I have run with these workflow and files before I upgraded O2 (previous version was ~3 weeks old) with no problem. Now, I have a strange error (see the full log below). The workflow misses a files o2simdigitizerworkflow_configuration.ini which should be only required by the digitizer workflow. (The subsequential error is due to the fact that the digit reader has not read anything.)

Hello @slokos

The FIT digit readers were missing a feature which all other worklows had: possibility to inject the timestamps and TF orbit from the simulated or reconstructed data aux. file. By default it looks for the o2simdigitizerworkflow_configuration.ini where digitization time info is stored.
You can disable this feature by

o2-fv0-digit-reader-workflow  --hbfutils-config none ...

Thank you very much , @shahoian for the quick answer. This is the solution for my problem.
