ERROR: The JSON engine cannot be found

[pbad]

Dear team,

In one of the program I fetch data from an external API and I use the JSON LIBNAME engine to parse the resulting JSON data. The problem, the codes are running fine in SAS 9.4 32 bit SAS but I am getting the following errors in SAS 9.4 64 bit.

The JSON LIBNAME engine was introduced in SAS version 9.4 M4, so the code should run in both the enviroment i.e. 32 bit SAS and 64 bit SAS but surprisingly the error is popping up in 64 bit SAS only. Please let me know if someone has solution.

Thanks in advance.

The error I am getting:-

ERROR: The JSON engine cannot be found.

ERROR: Error in the LIBNAME statement.

26 data sasprod.prospects; set sign.prospects; run;

ERROR: Libref SIGN is not assigned.

NOTE: The SAS System stopped processing this step because of errors.

WARNING: The data set SASPROD.PROSPECTS may be incomplete. When this step was stopped there

were 0 observations and 0 variables.

27 data sasprod.root; set sign.root; run;

ERROR: Libref SIGN is not assigned.

The codes used are

filename response temp;

proc http

   url="https://api.xx.io/api/xx/xxxx/xxxxxxxx/xxxx/"

   method="GET"

   webusername="XXXX"

   webpassword="XXXX"

   out=response;

run;

libname sign JSON fileref=response;

I am looking forward to hear from you.

Thanks

The JSON libname engine was added in 9.4M4 (see this blog post).  You'll need to make sure your 64-bit SAS is updated to the latest maintenance release too -- updating just 32-bit SAS won't be enough (different bits) even on the same machine.

Update from original poster:

Thanks for your replies. The problem is solved now 

M3 catalog was used in SAS 9.4 M4 installation, so it is a mistake from our end.

Hi Thanks for your reply. 64 bit also is SAS 9.4 M4.

@pbad,

This is Linux or Windows?

If Linux, verify these exist:

/<SASHome>/SASFoundation/9.4/sasexe/tkinstjson.so
/<SASHome>/home/SASFoundation/9.4/sasexe/sasejson
/<SASHome>/home/SASFoundation/9.4/sasexe/sasjson
/<SASHome>/home/SASFoundation/9.4/sasexe/tkejson.so

If Windows, verify these exist:

\SASHome\SASFoundation\9.4\core\sasEXE\sasejson.dll
\SASHome\SASFoundation\9.4\core\sasEXT\tkejson.dll

Hey,

Thanks for the reply 🙂

Yes all the mentioned files are available but for SAS 9.4, the locations are slightly different, as mentioned below:-

C:\Program Files\SAS 9.4\SASFoundation\9.4\core\sasexe

C:\Program Files\SAS 9.4\SASFoundation\9.4\core\sasext

I am planning to raise the ticket with SAS also.

Error still same.

27 libname sign JSON fileref=response;

ERROR: The JSON engine cannot be found.

ERROR: Error in the LIBNAME statement.

28 data sasprod.prospects; set sign.prospects; run;

@pbad,

Yes, please open a track and our Windows Technical Support will assist you. From my point of view, something went wrong during the installation or upgrade...

Dear all,

Thanks for your replies. The problem is solved now 🙂

M3 catalog was used in SAS 9.4 M4 installation, so it is a mistake from our end.
