Index Mapping Service fails

[glhoste]

Hi, I just installed FullTextSearch app (inc. bookmarks, Elasticsearch, files, tesseract) on the latest version of NC (20.0.5). While indexing for the first time (occ fulltextsearch:index), I get the following error. fulltextsearch:test raises no error. My system : Ubuntu 18.04, PHP7.4, Apache

An unhandled exception has been thrown: TypeError: Return value of OCA\FullTextSearch_Elasticsearch\Service\IndexMappingService::indexDocumentNew() must be of the type array, string returned in /var/www/cloud/apps/fulltextsearch_elasticsearch/lib/Service/IndexMappingService.php:89 Stack trace: #0 /var/www/cloud/apps/fulltextsearch_elasticsearch/lib/Service/IndexService.php(197): OCA\FullTextSearch_Elasticsearch\Service\IndexMappingService->indexDocumentNew() #1 /var/www/cloud/apps/fulltextsearch_elasticsearch/lib/Platform/ElasticSearchPlatform.php(222): OCA\FullTextSearch_Elasticsearch\Service\IndexService->indexDocument() #2 /var/www/cloud/apps/fulltextsearch/lib/Service/IndexService.php(375): OCA\FullTextSearch_Elasticsearch\Platform\ElasticSearchPlatform->indexDocument() #3 /var/www/cloud/apps/fulltextsearch/lib/Service/IndexService.php(326): OCA\FullTextSearch\Service\IndexService->indexDocument() #4 /var/www/cloud/apps/fulltextsearch/lib/Service/IndexService.php(204): OCA\FullTextSearch\Service\IndexService->indexDocuments() #5 /var/www/cloud/apps/fulltextsearch/lib/Command/Index.php(410): OCA\FullTextSearch\Service\IndexService->indexProviderContentFromUser() #6 /var/www/cloud/apps/fulltextsearch/lib/Command/Index.php(273): OCA\FullTextSearch\Command\Index->indexProvider() #7 /var/www/cloud/3rdparty/symfony/console/Command/Command.php(255): OCA\FullTextSearch\Command\Index->execute() #8 /var/www/cloud/core/Command/Base.php(169): Symfony\Component\Console\Command\Command->run() #9 /var/www/cloud/3rdparty/symfony/console/Application.php(1000): OC\Core\Command\Base->run() #10 /var/www/cloud/3rdparty/symfony/console/Application.php(271): Symfony\Component\Console\Application->doRunCommand() #11 /var/www/cloud/3rdparty/symfony/console/Application.php(147): Symfony\Component\Console\Application->doRun() #12 /var/www/cloud/lib/private/Console/Application.php(215): Symfony\Component\Console\Application->run() #13 /var/www/cloud/console.php(100): OC\Console\Application->run() #14 /var/www/cloud/occ(11): require_once('/var/www/cloud/...')

Many thanks, Guillaume

Did you check for elasticsearch errors in its logs? In my case, the issue seems to have been caused by too small heap size setting for elasticsearch, which crashed then with out of memory.
