Troubleshooting

Common problems

The action is missing, or runs fail with “service provider not found”

The runtime is loading the extension bundle. Remove extensionBundle from the host.json the runtime reads (build and publish output), and in Azure delete the AzureFunctionsJobHost__extensionBundle__* app settings. Check FUNCTIONS_INPROC_NET8_ENABLED=1.

MissingServiceProviderConnectionParameterValues

connections.json has "parameterValues": {}. Use { "templateFolder": "" }.

WorkerUnavailable: the worker was not found or is incomplete

lambogenius-liquid-worker/ is missing or lacks its .runtimeconfig.json. Deploy the publish output, not the build output.

The action runs several times

The runtime retries 5xx failures even with retryPolicy none. Leave LiquidCompose__PlatformRetries at false, and put retryPolicy inside inputs.

TransformationTimeout on the first run only

The deadline includes compiling the C# block, which takes a few seconds on a fresh worker. Raise timeoutSeconds.

UnknownFilter

Filters use C# casing: Upcase, not upcase.

InvalidOutputJson

A value without ToJson, quotes around ToJson, a trailing comma from a loop, or text after the JSON value.

ScriptExecutionFailed

A null or missing value reached a helper (add Default: ''), Default turned a number into a string, or the helper threw.

Blank lines in text output

Use a dash on the right of tags (-%}) and end lines with the tag.

An XML template from Microsoft's Liquid action renders nothing

This action does not convert XML to JSON: read it with XmlValue and XmlValues.

The build fails with MSB3030 in a deep folder

The Windows 260-character path limit. Move the project to a shorter path.
