### Version 5.2.2 ### Link to Minimal Reproduction _No response_ ### Steps to Reproduce I update my project to angular 13 (from angular 7) Configurare a linechart with a series array using a for loop and push the data ``` for (const value of this.valuesToShow) { option.series.push({ ...value }) } ``` Push is undefined to the property` (property) EChartsOption.series?: SeriesOption ` ### Current Behavior The configuration doesn't see the series as array so I cannot use the function push. I tried to cast the type of the data and also the type of the series as array and `SeriesOption$1[]` but this type in particular is not recognize. The only way I found to avoid this problem in local is touch the lib and convert the series: `series?: SeriesOption$1[];` ### Expected Behavior I expect that i can push an array into a series option as it configure on the lib: `series?: SeriesOption$1 | SeriesOption$1[];` Although seems that only the first type is detected. ### Environment ```markdown - OS: - Browser: - Framework: ``` ### Any additional comments? _No response_ -- This is an automated message from the Apache Git Service.
