Bug Report

"As soon as you ask anything, the aforementioned error message appears, and nothing else is possible. When I switch to a language model like GPT-4All Falcon, the queries work but are very slow (not sure if that's relevant)."

Steps to Reproduce

1. By Settings/Device I changed to CPU

Expected Behavior

Your Environment

• 16 Ram installiert
• GPT4All version: v3.6.1
• Operating System: Windows 10 Pro
• Chat model used (if applicable): EM German Mistral

I have got similar error:

Error: Failed to parse chat template: 1:1: error: Unexpected exception occurred during template processing. Exception: std::bad_alloc

and I am using OpenAI compatible endpoint running Qwen2.5-1.5B-Instruct-Q4_K_M.gguf with the default chat template being:

<chat>
{%- set loop_messages = messages %}
{%- for message in loop_messages %}
    {%- if not message['role'] in ['user', 'assistant', 'system'] %}
        {{- raise_exception('Unknown role: ' + message['role']) }}
    {%- endif %}
    {{- '<' + message['role'] + '>' }}
    {%- if message['role'] == 'user' %}
        {%- for source in message.sources %}
            {%- if loop.first %}
                {{- '### Context:\n' }}
            {%- endif %}
            {{- ('Collection: ' + source.collection + '\n'    +
                 'Path: '       + source.path       + '\n'    +
                 'Excerpt: '    + source.text       + '\n\n') | escape }}
        {%- endfor %}
    {%- endif %}
    {%- for attachment in message.prompt_attachments %}
        {{- (attachment.processed_content + '\n\n') | escape }}
    {%- endfor %}
    {{- message.content | escape }}
    {{- '</' + message['role'] + '>' }}
{%- endfor %}
</chat>

and this error comes only when I am using LocalDocs to inquire about documents. Is there any remedy?
