[ErvinN]

Hi all and @nh.schottfam

I would like to ask if you can help me with below piston that reporting "Invalid empty variable name null" and does not set anything to the variable it just stay empty. Is this bug or I'm doing something wrong?

As per the logs, maybe change the variables to string as opposed to dynamic.
It looks to me that you are trying to save text.

[ErvinN]

Still the same

Please do an HPM repair of your webcore install (if you did HPM install)

Otherwise please update to latest code and let me know if you still have an issue

After updating webcore, clear your browser cache, and edit this piston to ensure the code is correct and save.

[ErvinN]

Issue still persist.
I repaired the webcore via HPM (got latest version 20211005) and following tried to run pistion on firefox and chrome but still the same result on both.

So when I imported your piston, the variable initialize section is missing.

When I deleted and re-created the variables, it came back.

What are you using for your IDE url?

Can you delete the variable and recreate it in the define section?

Really strange - never seen this before.

[ErvinN]

Thanks, after I deleted the variable and also deleted the "set variable" line and recreated them, piston start working properly. Does it mean I have to do the same on all my about 70 pistons?

I'm using Chrome and Firefox latest versions to work on webcore.
Is that answered your question regarding of IDE url?

[eibyer]

Strange thing is enclosing status ON or status OFF in quotes doesn't throw an error but then the state looks funky with the quotes without text modification.

Edit: Setting variable value using Expression "Status ON or OFF" works though.

[ErvinN]

I tried to set it up also via Expression but that time (before the REPAIR) it was not working.

[eibyer]

Ah that is strange. I did encounter the same invalid variable message you mentioned when I first imported your piston.

[ErvinN]

Definitely there is some bug. I have to review all my 70 pistons if there are some affected one
