Workaround
To circumvent this issue, complete the following steps:
- Take a backup (copy) of the following file:
SASHome/SASFoundation/9.4/lua/modimpsvr/sas/risk/modimp/rskmimpl_rest_api.lua - Edit the file above and locate the following line (line number 669):
local ETag = string.match(header_string, 'ETag: (W/".+?")') - Replace the line above with the following:
local ETag = string.match(header_string, 'ETag: (W/"[^"]+")'
Note: If you have customized Lua files in SASCustomCode/, then that file needs to be modified instead of the file in SASFoundation.
