Steps to reproduce:
from torch.optim.adam import Adam
Adam() # when lsp tries to give arguments hint in the mini buffer. The following error is invoked.
Error processing message (error "Failed to handle #s(hash-table size 65 test equal rehash-size 1.5 rehash-threshold 0.8125 data (kind plaintext))"). [5 times]
Most likely the error seems to be within emacs bounds.
