Hi all, I am currently trying to build a Ros Pipeline using the JS Processor and then visualise it in the Dashboard or Data Explorer. Unfortunately, I have to restart the pipeline several times until the data runs through the pipeline. Enclosed you will find the error message. Do you have any idea where the problem is?
