@david-cuen Thanks for your patience and dedication to seeing this through. It would help a ton if you could find something reproducible. Let me know what you find and I can continue to try it on this end.

@david-cuen This is really weird. I was not able to replicate it. There is one more thing I may try later if I get some time. That is to make one template that big and try that.

In the mean time, I went back to look at the error message. "Premature EOF" and the fact that it was working on a windows box has be back to believing that a funky character or something is causing the error on the linux box. I wish we could narrow it down. Have you tried to install into another linux environment, EC2 for example, and see if you get the same issue? (That may tell us if it is a linux thing or if it is your one specific environment.) Also, someone mentioned to ask if you have any proxies running in front of FusionAuth?

@david-cuen I wasn't able to find much else out on Friday. Awesome that it looks like you have it narrowed down to the size. I will try to replicate this. I will let you know if I can.

@tim-clark Can you please point to the community discussion where this comes up? I could not find it in the issues.

@david-cuen sorry for the delayed response. I was unexpectedly out. Thanks for trying to dig a bit deeper. The message you definitely leads me to believe that it is either a specific theme or as you said a size thing. Both are a bit confusing to me as the size you mentioned for your themes does not seem that bit and you stated that you tried loading the themes in different orders and that did not seem to make a difference. I will see if I can dig a little deeper on these error messages and see if there is anything I can find.

@david-cuen Goodnews and badnews. The goodnews is that I imported the exact theme you pointed to and was able to copy that 11 times and not issues. My environment now has 26 themes. The badnews is that is not helping you. Sorry. I think we need to dig a little further. Based on the additional pages you mentioned (adding/editing tenant/application) I am wondering if something specific with the edits you have made to the themes. The fact that you change the order they are loaded in makes that less likely though. What are the sizes of the tpl folders for your themes?

@hemanth18pages raising the support ticket is the way to go for sure. It will be good to know if anyone else is experiencing this too.

@david-cuen perfect. I was copying themes, but will us that one and let you know what I find.

@david-cuen OK, I was able to get more than 10, but you're right about it possibly being the size. Is it possible for you to share the theme you are using with us or me individually? I don't want you to give away any secrets, proprietary info or share anything private if you can't but getting a look at the theme may help.

@bernardo-munz Did you play with the SameSite setting?
