Current Ignition Version: 8.3.1 Just upgraded from v7.9.21 to v8.1.48 (completed full round of testing) and now to v8.3.1 (doing testing now) Just in case someone else comes across a similar issue, `system.report.executeReport` was returning `None` for reports which worked without issue in v8.1.48 and which work fine when opened in the designer with the default parameters. I cannot find any error messages in the gateway suggesting what might be the cause. A workaround seems to be to open the report in the designer, close the report, save, and then try running the report again. That seems to be required for each individual report. Anyone else having this issue? UPDATE: I do see an error in the design tab with title of "Data Collection Errors" and message of "ERROR: JsonNull" before opening/closing/saving the report for the first time. UPDATE: try specifically opening each `parameter` and `script` in the **Data** tab and then open the **Design** tab and then **Preview**. That seems to resolve the "ERROR: JsonNull" error. UPDATE: Found an exception from the gateway... ```python java.lang.UnsupportedOperationException: JsonNull at com.inductiveautomation.ignition.common.gson.JsonElement.getAsString(JsonElement.java:188)

`system.report.executeReport` works, but I cannot make changes to these reports. ---

We encountered this internally. I’m actually currently working this. The various updates you posted, was this after the workaround or before? ---

Do you have a backup (from prior to the upgrade) you can send in to support? ---

The updates were after the workaround. I just had not gotten through all the reports yet. When I started going through the rest, I started seeing these other things. ---

Thanks for the files. This was really helpful in narrowing down the problem.
