FT0 and FV0 digit reader error, missing digitizer configuration

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.)

Thanks for the help in advance, Sandor

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.
