Hi folks,
it looks like that every single http request from our POS I Extensions towards our app url is failing with POS version 10.19.0.
Tested on multiple iPhones & iPads.
This happens for our (OpenFiskal) POS UI Extensions, but also for others.
Any clue?
We are using the “relative path mechanism” to do our http request:
await fetch(`/api/endpoint`);
Many thanks
Christof
Looks like this issue is related to this issue?
Yep. I tested a handfull of POS UI Extensions, they are all pretty much completely broken right now.
All are saying something like “cant find x”, “cant connect to server”, “not a valid url”.
@remy727 do you know someone from Shopify to tag here, so we can get Shopify eyes on this issue ASAP?
Hello @Alan_G, can you please take a look on this?
Thank you!
FYI: With the development server, everything works as expected.
Hey 
thanks for the report. We’re investigating this issue, if you have any further logs or information to share to reproduce that would help. Thank you.
@Christof_Zirkler are you experiencing this with all users on device or a subset of users?
We were able to test this on 3 devices, it happens on all 3.
@Aaron_Schubert the error we are getting back from fetch() on POS is
"/pos-print-extension/api/end-of-day-reports" cannot be parsed as a URL
@Christof_Zirkler we’ve identified the issue and have made a mitigation that will be applied on the next settings sync (You can force this by tapping on Connectivity icon in bottom left corner → Store data → Refresh all) Could you verify if this has mitigated the issue for you?
Many thanks Aaron! It works after Sync + POS App restart. 
hey @Aaron_Schubert I work with Derrick from this thread URGENT: Shopify POS 10.19.0 api.cart.addLineItem(variantId) has stopped working for newly-created variantIds , did you have anyone take a look on it? It’s affecting all of our apps
Hey @JV_Ferreira, yes we’re investigating this too.
Thank you, please keep us posted on the investigation updates @Aaron_Schubert
