Follow Filter don't work anymore

[bc2606]

When launching follow filter the following error happens.

terminate called after throwing an instance of 'ros::InvalidNameException' what(): Character [ ] at element [6] is not valid in Graph Resource Name [~exist intensity 500 to 4000]. Valid characters are a-z, A-Z, 0-9, / and _.

The installation is new on a ubuntu 18.04.4.
I don't know where it can come from.

Is it a known issue?

Thanks in advance for your help.

check on the YAML file , the name parameter should not contain any spaces .
