I saw your dummy file and was able to edit it myself.
I am having trouble with this particular record.
If you load the record below and scroll down to section B of the survey, you will see that there is a data entry error. I am trying to change the Murid Individual number from 128951 to 128921. I use pull data to retrieve information from the media file. I think this is part of the problem.
But at the same time, it seems like you are trying to reference the information within a repeat group using the pulldata function. In this case i would advise you go through this post discussed previously:
Hello i’m having exactly the same problem and i’ve read through the chat history.
I successfully made a dummy entry from another device tried editing some data types and they were actually successful.
However, i was able to do a location correction prior to the error but right now location type data still gives me the error “Submission failed the data server for your form or Enketo server is down…”.
Please any suggestions to get past this?
Edit: Turns out that after a while the error stopped completely. Keeping my fingers crossed as i continue.
