I have tried gojq

the input can be thousands of line of data.
so how to find at which line I am getting the error

Oh, you are asking how to find the line of input that contains the input that caused a jq error to occur; I completely misunderstood what you mean. :|

You could do that with something like:

try ["VALID", { sd: .user, ds: .user.officer[.user.jack] }] catch ["ERROR", input_filename, input_line_number, .]

That will output ["VALID",<resultsofyourexpression>...] if it did not error; and ["ERROR", <filename>, <linenumber>, <errormessage>] if it errored; in that case you would get:

["ERROR","<stdin>",11,"Cannot index object with null"]

Note that it outputs 11 because that is the line on which the input that triggered the error ends.

what does this input_line_number depicts? as the input data is about 8-9 lines not greater then 11

@MGoyal01 i input_line_number will be the last line in the input that the current input value was part of. In the example above i guess 11 is the ending } of the single input value. Example with multiple input values:

$ jq -c '{line: input_line_number, value: .}' << EOF
123 {"a":1,
"b":2} "hello"
EOF
{"line":1,"value":123}
{"line":2,"value":{"a":1,"b":2}}
{"line":2,"value":"hello"}

Could you elaborate a bit more about how your input looks like? maybe a bit more detailed example input JSON?
