Error message suppressed and incorrect result returned

[mgirlich]

The following gives an jq error but the error is actually not thrown. Further, we get a length 1 vector instead of a length 2 as expected.

jqr::jq(c('{"a": 1}', '2'), ".a")
#> 1

again, jq expects json https://github.com/ropensci/jqr/issues/79#issuecomment-578194808

slightly modified example with an array as input:

jqr::jq(c('{"a": 1}', '[2]'), ".a")
#> 1

@jeroen any thoughts on this issue. it does appear that it should throw an error

echo '{"a": 1} "2"' | jq '.a'
# 1
# jq: error (at <stdin>:1): Cannot index string with string "a"

@mgirlich Sorry about the delay. We have limited bandwidth to work on this. Fastest way is if you have submit a PR with a fix/change
