[sarincm]

Hi @clarketm
when i am creating json file for indexing based on md files.it is getting struck in between.but didnot display any errors

/node_modules/hugo-elasticsearch/lib/hes.js:187 throw _iteratorError; ^ YAMLException: end of the stream or a document separator is expected at line 7, column 1: ^ at generateError (/node_modules/js-yaml/lib/js-yaml/loader.js:167:10) at throwError (/node_modules/js-yaml/lib/js-yaml/loader.js:173:9) at readDocument (/node_modules/js-yaml/lib/js-yaml/loader.js:1539:5) at loadDocuments (/node_modules/js-yaml/lib/js-yaml/loader.js:1575:5) at load (/node_modules/js-yaml/lib/js-yaml/loader.js:1596:19) at Object.safeLoad (/node_modules/js-yaml/lib/js-yaml/loader.js:1618:10) at module.exports (/node_modules/gray-matter/lib/parse.js:12:17) at parseMatter (/node_modules/gray-matter/index.js:109:17) at matter (/node_modules/gray-matter/index.js:50:10) at Function.matter.read (/node_modules/gray-matter/index.js:180:16)

is there any way to show the md file name or line number which causing this error..i have 100s of md files so it is very hard to find which md file is corrupted or causing the error
Thank you
