Steps to reproduce

Block of TSP when error was generated:
function update()
dmm.measure.read(defbuffer1)
local percentChange = {}
for i = 0, (dmm.measure.count - 1) do
percentChange[i
end
end

Expected behaviour

No error

Actual behaviour

Error returned in TSP Command Autocomplete Output:
[Error - 10:33:57 AM] Request textDocument/completion failed.
Message: Request textDocument/completion failed with message: Invalid regular expression: /percentChange[i/: Unterminated character class
Code: -32603

Another example:
By typing line:
buffer.write.reading(App_buffer, defbuffer1[e
(Attempting to type buffer.write.reading(App_buffer, defbuffer1[endindex])

Returns:
[Error - 11:06:44 AM] Request textDocument/completion failed.
Message: Request textDocument/completion failed with message: Invalid regular expression: /defbuffer1[e/: Unterminated character class
Code: -32603

This is an error in line 50 of /server/src/completionProcessor.ts wherein I foolishly decided to use an un-escaped string variable as the text of a regular expression.

Resolved in v0.4.2.
