External script error

[markfree]

I'm trying to start a Curl script from Administration - Scripts but it keeps giving me an error.

For now the script calls a simple Curl that reads a JSON file and receives a JSON response.

IN_JSON="rde_post.json"
OUT_JSON="rde_return.json"

curl \
    --netrc-file /usr/lib/zabbix/externalscripts/rde/teste/.netrc/ \
    --request POST \
    --header "Content-Type: application/json" \
    --data "@${IN_JSON}" \
    --output ${OUT_JSON} \
    http://URI...

I can execute this script correctly from the command line.

In Zabbix, I use the following line to start the script:

/usr/lib/zabbix/externalscripts/rde/test/curl_test.sh

When I try to start it from the trigger menu at the Dashboard, it gives me the error below.

Cannot execute script.
Warning: Couldn't read data from file "rde_post.json", this makes an empty
Warning: POST.

I'm not sure, but the issue seems to be related to file permissions. I changed files ownership to Zabbix user but the error repeats itself.

rwxr-xr-x 1 zabbix zabbix 369 Aug 24 11:40 curl_test.sh

rw-r--r-- 1 zabbix zabbix 849 Aug 24 10:40 rde_return.json

This is a newly installed Zabbix 5.4.3.

Any help is apreciated.
Thanks.

Zabbix user, which server is run as, has probably home directory set to something like /var/lib/zabbix, so it tries to read those files from there. For a start, I'd try setting full path to those:

IN_JSON="/full/path/to/file/rde_post.json"
OUT_JSON="/full/path/to/file/rde_return.json"

Thank you dimir
Using full path works.
