[I] [Bug] Empty Dataset as target for transform results in Illegal condition error. [echarts]
ash-hannigan opened a new issue, #20788:
URL: https://github.com/apache/echarts/issues/20788
### Version
5.6.0
### Link to Minimal Reproduction
https://echarts.apache.org/examples/en/editor.html?code=PYBwLglsB2AEC8sDeAoWsAeBBDEDOAXMmurGAJ4gCmRA5JALZW0kC-ANCeTvkaqWUo1YtAG4BDADYBXZm07o8VAE4QqhWAG0S6fgNgATcWHFKwASQN08wacoDGVALQAzCJLAraC_RWp1JCGhmHwEqaHtgA2EkTDoJGRDYcjojT0ZmWFYdLJIAXR800yowIm0BPQEbO0cygpz0CCsRaoc5AQ4cytIm61s213dPZW8G2BdlYAYAEWNii2baVsdR_TJlcWg8F2BlBj4x9D9hWjcPL1D9SOg3AHMDtYEDCCYtqGg6aHEmVcf0WngtHiUlkAEYWH9smsoaQYXkUKwANxAA
### Steps to Reproduce
Create an echart option with a source dataset that has an empty array as the source.
This is a common scenario for when data is loading from a remote API.
Create a transform dataset that references this empty dataset.
Create a simple series that references the result of this transformed dataset.
[example: empty dataset source](https://echarts.apache.org/examples/en/editor.html?code=PYBwLglsB2AEC8sDeAoWsAeBBDEDOAXMmurGAJ4gCmRA5JALZW0kC-ANCeTvkaqWUo1YtAG4BDADYBXZm07o8VAE4QqhWAG0S6fgNgATcWHFKwASQN08wacoDGVALQAzCJLAraC_RWp1JCGhmHwEqaHtgA2EkTDoJGRDYcjojT0ZmWFYdLJIAXR800yowIm0BPQEbO0cygpz0CCsRaoc5AQ4cytIm61s213dPZW8G2BdlYAYAEWNii2baVsdR_TJlcWg8F2BlBj4x9D9hWjcPL1D9SOg3AHMDtYEDCCYtqGg6aHEmVcf0WngtHiUlkAEYWH9smsoaQYXkUKwANxAA)
[example: valid dataset source](https://echarts.apache.org/examples/en/editor.html?code=PYBwLglsB2AEC8sDeAoWsAeBBDEDOAXMmurGAJ4gCmRA5JALZW0kC-ANCeTvkaqWUo1YtAG4BDADYBXZm07o8VAE4QqhWAG0S6fgNgATcWHFKwASQN08wacoDGVALQAzCJLAraC_RWp1JCGhmHwEqaHtgA2EkTDojT0YQ2HI6CRlmWFYdLJIAXR8E0yowIm0BPQEbO0cypHTZIgBGACYAOib2Q2MSiCZmgHYAFgAGIYBWFoBOIYAOLuhxfpEGqibaDnqpRthWtoBmLoTe5abhsfGmmfnYReWxbbWNgpz0CCsRaoc5AQ4cytI72stm-rncnmU3lesBcymADAAIsZihYPrQvo4ofoyMpxNA8C5gMoGHxoeg_MJaG4PF5QvpItA3ABzUnYgQGPrhPBQaB0O4hMmkWjwWhpR7rQXZbFS0gyvIoVgAbiAA)
### Current Behavior
echarts throws an error with:
`Can not find dimension info via: sensor. Existing dimensions: [] . Illegal condition {"dimension":"name","=":"value1"}.`
This occurs even with showLoading();
### Expected Behavior
echarts returns an empty dataset source.
The filter should fail and return an empty dataset.
### Environment
```markdown
- OS: Windows 11
- Browser: Edge / Chrome / Firefox
- Framework: React 19
```

@helgasoft, this works thank you.
Something to note the dimension array only needs to be the minimal required, which is handy!
For example, if the dataset looks like:
`[{"name": "cheesecake", "datetime": 1740525269, "value":2, "created": 1740525269, "modified": null, "comment": "", "source": 321545}, ...]`
and only certain properties are required, using a subset in dimensions still works:
`"dimensions": ["value", "datetime", "name"]`

add ```dimensions: ['value','datetime','name'],``` in first dataset
📌 please close issue if problem solved.
