Vanilla Code

While i develop customization i met a problem while publishing\building screen, related to QuerySelector id “formSlotA01” isn`t unique
 

Error occured during HTML merge for 'EP208000', original source will be used instead. Error: Error: Element ids are not unique: id=formSlotA01 tags=QP-FIELDSET,QP-FIELDSET


 

My code

I renamed it manually. Second formSlotA01 to formSlotB01 and it is published correctly. So i confused, it`s a system bug or im miss something?

Hi, I just get similar error on my side, but in my case, I can not find any duplicate id in the code, the error message shows :

Error occured during HTML merge for 'PO301000', original source will be used instead. Error: Error: Element ids are not unique: id=tab-TrueCommerce_PO tags=QP-TAB,QP-TAB; id=form-TrueCommerce_PO tags=QP-TEMPLATE,QP-TEMPLATE; id=divColumnA-TrueCommerce_PO tags=DIV,DIV; id=fsUDF-TrueCommerce_PO tags=QP-FIELDSET,QP-FIELDSET; id=fsTSNStatus-TrueCommerce_PO tags=QP-FIELDSET,QP-FIELDSET

 

However, I can not find any duplicate ID in my extension file, I’m wondering if the validation will first remove the prefix for those elements?

Here is the screenshot of my extension HTML and the search result for the IDs from this page in frontSource folder:
