Issue still exists in 9.2.0 Native. Adding error handling does not seem appropriate, synchs should be queued. For what it is worth, I found that the Take Picture Advanced Nanoflow Java Action must be performing a synch as when I removed a manual synch after this function the error went away. Perhaps others are using functions that they are unaware are already synching and a manual synch request should then not be performed.
Hi Wilfred, Do you have the same problem?
No updates yet; mendix was asking for a test project and that is not possible for use to share. Hopefully Mendix wil admit soon that this is a bug.
We are also having this issue after the upgrade. Did any of you already convince Mendix?
