exists failed, could not prepare: Could not parse response into a JSON object

Hi Team,

I m using 2.1.7 Gatling.

When i run scripts for 100 users, i get following error after saving record.

Error Count Percentage

jsonPath($.tbl0[0].catalogRowId).find(0).exists failed, could not prepare: Could not parse response into a JSON object: Unable to determine the current character, it is not a string, number, array, or object The current character read is ‘<’ with an int value of 60 Unable to determine the current character, it is not a string, number, array, or object line number 1 index number 0 ^

Json Path is correct. It will fail for some request.

Can any one help me on this

Regards
