When you run a SAS Visual Forecasting project using the Batch API code, the Loading project data... step might fail with one of the following error messages:
Loading project data...
NOTE: 502 Bad Gateway
Response status: 502
ERROR: An invalid response was received.
OR
Loading project data...
WARNING: Unable to read data from Web server, errno = 104 (The connection was reset by a peer.).
ERROR: The tcpSockRead call failed. The system error is 'The connection was reset by a peer.'.
ERROR: Connection has been closed.
When you try to open the SAS Visual Forecasting project, a window is displayed that states, Opening project... and Model Studio stops responding, as shown in the following image:
After a few minutes, a new window is displayed that states, An error occurred. Please contact your system administrator. Upon clicking Show details, you might encounter one of the following error messages:
The problem occurs when a table in the SAS Visual Forecasting project caslib is unable to load.
Workaround
To circumvent this issue, run the SAS Visual Forecasting project again using the Batch API code before opening the project in Model Studio. Prior to submitting the code, comment out the %ABORT statement in the Loading project data... step. For reference, see the highlighted line in the following sample of the code:
** Load project data...
******************************************************************************/
%put Loading project data...;
proc http
method="PUT"
url="&protocol.://&host.:&port./forecastingGateway/projects/&projectId./dataState"
out=resp;
headers
"Authorization"="bearer &authtoken.";
run;
%put ERROR: An invalid response was received.;
/* %abort; */
%end;
