routeros 6.42.5 and 6.42.6 script /file not working as expected.
the device is RB450Gx4

This code:
:local ddnshost "google.com"
:log info "Hostname = $ddnshost"
:local ddnsip [:resolve $ddnshost]
:log info "IP = $ddnsip"
/tool fetch mode=https address=[:resolve ifconfig.co] port=443 host="ifconfig.co" \
src-path="/ip" dst-path="/currentip.txt"
:log info "got here"
:local currentdnsip [/file get "currentip.txt" contents]
:log info "currentip.txt = $currentdnsip"
--------------------------
Upon the first running the output in the LOG ends with "got here".
Yet, the file was created and the contents are correct.

If I remove that file and rerun the script the results are the SAME.

If I do NOT remove the file and then rerun the script the output does include the info entry with "currentip.txt = ...." with the correct result.

I have run this a zillion times and the two alternatives always produce the same inconsistent results.
What is wrong here?

Thanks for any help!

What is wrong here?

After the fetch, but before reading the file, put a short delay, like 2 seconds:
Unfortunately, this is how it works - the file that has just been downloaded/created locally - is not visible immediately, though the fetch command already finished its job. This is MikroTik's internal issue (maybe some disk buffering) - known issue and known solution.

Thanks!

Wouldn't it be wise to add this "workaround" to the manuals, guides, howots, etc. spread all around the internet? I didn't see this workaround and thus fell into the bug.

How long has this been a problem?

Thanks for the advice!
