@mlipovaca , can you provide more details? Can you try to reproduce the error in test?

[mlipovaca]

@zjklee it’s not reproducable directly on calling Handlebars func, it was giving error on Startup.cs in C#. We restarted the API and then it worked itself. Also we’re on version v2.1.2. Is the version on v2.1.3 this type of issue fixed as I saw it was released two days ago ?

[oformaniuk]

@mlipovaca , in v2.1.3 another issue is fixed - it happened in parser when template was invalid. This error seams to happen in runtime. Hard to tell what is the cause, it might be a legit OutOfMemoryException if you run out of memory as it happened during dictionary resizing: HandlebarsDotNet.Collections.DictionarySlim'3.Resize. If you have a lot of compiled templates, you may want to have a look at SharedEnvironment feature.
