read_obs_convert: error converting vobs data

[carlos9917]

Hello.
I am facing a very strange error in read_obs_convert. I tried reducing the vobs file I am having problem with to the minimum, but I still get the same error:

Loading required package: ggplot2
Loading required package: shiny
Loading required package: harpSpatial
here() starts at /dmidata/users/cap/R/harp-verif
Reading: ./TEST/vobs2022110400
Writing to: SYNOP in /data/projects/nckf/dan
vobs2022110400.txt
ra/verification/OBSTABLE/OBSTABLE_2022.sqlite
<Rcpp::exception: near ".1": syntax error>
[1] "FAILURE dbSendQuery 1 / 20"
[1] "near ".1": syntax error"
test_error_vobs.R.txt

I've no idea what is wrong, the two lines have the correct number of columns but I keep getting this error.
If I delete the field TM it works, but I have used that parameter before, not sure why is a problem now...sometimes I see the message "trying to read Tmin.1"
I have attached an example script and example data, renamed both as .txt since github does not seem to accept .R or files with no suffix.
Thanks for any help
Carlos
