I am working through some of the great tutorials on DP1 data. I am having some issue when running the tutorial 304.1. PSF analysis for cosmology. I am currently running it as written in this version.
In section 2 when you run the query for the specific visit_id as a job (job = rsp_tap.submit_job(query), I am getting the error “DALQueryError: Query Error: ClassCastException:null”. I have not been successful in discerning what is causing this error within the query.
Dear @rnichols , thank you for your post. I was not able to reproduce your error using release r.29.1.1. Is this the same image that you are using? Would you mind running the cell again, or re-starting the kernel and trying again?
DP1 tutorial 103_3 on TAP access has a similar suggestion for another type of DAL error:
Hi, Thank you for the feedback. I am trying to run the same image as written in the tutorial and have not altered it. I have tried rerunning the cells, restarting the kernel, and rerunning the TAP statement right before the query using both the recommended release today (8.19.25) and the earlier version r.29.1.1. I all cases I continue to get the same error.
