Hi @nathank,
sorry for my late reply and thank you very much for your help. 
We’gve managed to get the config displayed in the dashboard.
Unfortunately, we specified the wrong path for the upload, i.e., the experiment folder.
The config is uploaded and displayed correctly when we specify offline run folder.
Example
old : wandb sync …/experiment_name
new : wandb sync …/experiment_name/wandb/offline-run-20220515_002356-jdlxek9r
Apparently, now, we get a new error:
.wandb: ERROR Metric data exceeds maximum size of 10.4MB (12.4MB)
wandb: ERROR Summary data exceeds maximum size of 10.4MB. Dropping it.
done.
However, the configuration is displayed correctly on the website.
Thanks again for your help and if we can’t get the new error under control, we’ll ask in a new issue.
Bests,
Cedric and Jannis
