Problem in parsing claim having type of table

[deependera]

Hi, There seems to be some problem with following piece of code in utils.lua script line 180

for i = 1, #header_names do
local header, claim
header = header_names[i]
claim = header_claims[i]
kong.service.request.clear_header(header)
for j = 1, #sources do
local source
source = sources[j]
if (source and source[claim]) then
kong.service.request.set_header(header, source[claim])
break
end
end
end

This piece of code will break if the claim has value type as table and because it will expect values to be either string or some other type and for this I think it need error handling
