Hi,  
I have added a new `julia` version on my university Cluster, moving from 1.7.2 to 1.8.3.  
I have add `ClusterManagers` and tried adding some processes, as I have always done. The problem is that I am not being able to add processes. If I run `addproc_lsf(1)` what I obtain is

`Error launching workers CapturedException(ClusterManagers.LSFException(""), Any[(lsf_bpeek(manager::LSFManager, jobid::SubString{String}, iarray::Int64) at lsf.jl:58, 1), (lsf_launch_and_monitor(manager::LSFManager, launched::Vector{Distributed.WorkerConfig}, c::Condition, jobid::SubString{String}, iarray::Int64) at lsf.jl:78, 1), (#31 at lsf.jl:105 [inlined], 1), ((::Base.var"#929#934"{ClusterManagers.var"#31#32"{LSFManager, Vector{Distributed.WorkerConfig}, Condition, SubString{String}}})(r::Base.RefValue{Any}, args::Tuple{Int64}) at asyncmap.jl:100, 1), (macro expansion at asyncmap.jl:234 [inlined], 1), ((::Base.var"#945#946"{Base.var"#929#934"{ClusterManagers.var"#31#32"{LSFManager, Vector{Distributed.WorkerConfig}, Condition, SubString{String}}}, Channel{Any}, Nothing})() at task.jl:484, 1)]) Int64[] `

I checked that I added the path to the new `julia` version to the `bashrc`, I run `source` on it (inspired by [this](https://github.com/JuliaParallel/ClusterManagers.jl/issues/48) ) but it didn’t work.

Thank you in advance for your time:)
