Error 1055 when building VIP

Recommended Posts


I have a large package that contains about 700 VIs (many classes with a large inheritance tree) and very often when I build it, I get an error 1055 on some VI, not always the same one.

When this happens, I have to take the following steps :

- close LabVIEW 2019 SP1

- close VIPM 2020.3 (build 2540)

- delete the VI Object Cache

- go to ProgramData\JKI\VIPM\Cache and delete the Spec Database Datalog.sdd file Spec Datalog Summary.sds (don't ask me how long it took me before I tried that the first time)

- reopen LabVIEW and VIPM as admin

- then the build process has a chance to go through.


Any idea what the issue could be?

I just encountered this error for the first time (but then 4 times in a row) for a large project that has built for a year on the same tool versions. It only happens on our build server. I can't reproduce it on my local pc.

I'm running VIPM 2020.3 build 2540 with LabVIEW 2020 (20.0.1 64 bit)

I followed Antoine's recipe but still get the same error

ERROR: Error 1055 occurred at VIPM API_vipm_api.lvlib:Parse Build Return Message_vipm_api.vi

Possible reason(s):

Code:: 1055
Source:: Error 1055 occurred at Invoke Node in Library.Save__ogb.vi->Copy Project Library Files__ogb.vi->Build Application__ogb.vi->Build Application from Build File__ogb.vi->Build Application from Build File__ogb.vi.ProxyCaller

Possible reason(s):

LabVIEW: (Hex 0x41F) Object reference is invalid.
Error Conditions:
Copy Project Library error:
Source: C:\agent\_work\4\s\.src\xxx_class\xxx.lvclass
Target: C:\Users\xxx\AppData\Local\Temp\vpbtmp\src\LabVIEW\instr.lib\xxx\xxx_class\xxx.lvclass
