Foswiki SolrPlugin cannot add a topic

Question

I use this guide to install Foswiki from master github repository using Nginx as Webserver.

cd /<foswiki-dir>/tools
./solrindex topic=Main.WebHome

No topic is created and these errors appears

Not a HASH reference at /var/www/fw-prod/core/lib/Foswiki/Engine/CLI.pm line 113. Undefined subroutine &Foswiki::encode_utf8 called at /var/www/fw-prod/core/lib/Foswiki/Response.pm line 431. BEGIN failed--compilation aborted at /var/www/fw-prod/core/lib/Foswiki.pm line 646. Compilation failed in require at ./solrindex line 30. BEGIN failed--compilation aborted at ./solrindex line 30. Can't call method "finalize" on an undefined value at /var/www/fw-prod/core/lib/Foswiki/Engine/Legacy.pm line 72. END failed--call queue aborted at ./solrindex line 30.

Can you help me please?

Answer 1

The posted error message refers to

Not a HASH reference at
/var/www/fw-prod/core/lib/Foswiki/Engine/CLI.pm line 113.

That part of the code varies considerably between versions. In 2.1.2 it is

113     my %uploads;

And in 2.0.3 it is

113 sub finalizeHeaders { }

Neither makes sense of the message. So can you tell me what Foswiki version you are running?

The message:

Undefined subroutine &Foswiki::encode_utf8 called at /var/www/fw-prod/core/lib/Foswiki/Response.pm line 431.

seems to suggest something wrong in the environment. Foswiki::encode_utf8 is defined in Foswiki.pm. Either you have an old version, or the code does not find Foswiki.pm. Strange, since it did find Foswiki.pm but did not compile, according to:

compilation aborted at /var/www/fw-prod/core/lib/Foswiki.pm line 646

Anyway, for debugging in and Apache/Foswiki configuration I use (from my makefile):

 FOSWIKI_HOME=/home/bram/devfoswiki/core  
 FOSWIKI_LIBS=${FOSWIKI_HOME}/lib:${FOSWIKI_HOME}/lib/CPAN/lib

 export FOSWIKI_HOME=${FOSWIKI_HOME}; export FOSWIKI_LIBS=${FOSWIKI_LIBS}

before executing the command line. Maybe that will help.

In your response, can you please refer to the versions of software you are using? It helps understanding the error messages.
