This error has appeared on 5 or 6 of my company's surveys. All of these began just after the 3.3 release on 2/26. In each survey, there is a random field that receives this error. Prior to the appearance of these errors, reports for all of these surveys had been generating without issue. No changes were made by us. The only common factor that I can see for the fields mentioned in the error messages is that they are fields within repeats. I published a copy of one of these surveys, but the problem persisted. I also tried removing the tag that was prompting the error. After that, I received the error message for the next field within that repeat. It did not give an error for the very first field in the repeat.
UPDATE: The problem has been solved. If the repeat name is MT, the field name cannot start with MT as in MT_Amount1. When all field names that started in that manner were edited, with those letters being removed, I was able to successfully generate reports. I'm sure this is related to the 3.3 update. Can anyone explain why it might be incorrect to start a field name with the same letters as the repeat name?
This was a bug discovered late in release testing, related to an enhancement introduced to specify a field by using <tablename>.<fieldname> (this was introduced to enable referencing a field in the parent table inside a repeat section). We will be addressing this issue in the near future.
Thanks for your response. Do you have an estimated time frame? I'm trying to decide if I should go ahead and fix our surveys now, which will be quite time consuming, or wait on ESRI's fix. We rely heavily on those surveys and need them up and running as soon as possible.
The fix for this issue should be applied to the website by the end of next week (hopefully around 14/15th March) but due to testing and release certification could vary slightly. We will keep you updated once available. If you can wait I would suggest that is the best option, as other changes you make as a workaround may require changes to question names/fields or repeat names, which will change the schema of your survey and could result in data loss.
This issue has already been resolved on the website and verified as fixed. If you are still encountering an issues the cause could be different. Can you please provide more details of the issue or a copy of your xlsx form and custom report to be able to reproduce?
