Manipulate the CanvasContent1 value with REST API

Hi !

I am currently strugling to update the CanvasContent1 html of a page USING the sharepoint REST API;

I tried the savepage method , but it return null without altering my page .

Any ideas ?

 "__metadata": {
 "type": "SP.Publishing.SitePage"
 },
 "CanvasContent1": "[{\"controlType\":4,\"id\":\"ed2476c7-994a-4a07-a322-8afe873c05f2\",\"innerHTML\":\"<p>Hello world in a Text Web Part from Power Automate!<br></p>\",\"position\":{\"zoneIndex\":1,\"sectionIndex\":1,\"controlIndex\":0.5,\"sectionFactor\":8,\"layoutIndex\":1},\"addedFromPersistedData\":true},{\"controlType\":3,\"webPartId\":\"c70391ea-0b10-4ee9-b2b4-006d3fcad0cd\",\"position\":{\"zoneIndex\":1,\"sectionIndex\":1,\"controlIndex\":1,\"sectionFactor\":8},\"id\":\"5f80a41e-a354-4bdf-9b21-42539ba00d98\",\"addedFromPersistedData\":true,\"reservedHeight\":127,\"reservedWidth\":776,\"webPartData\":{\"id\":\"c70391ea-0b10-4ee9-b2b4-006d3fcad0cd\",\"instanceId\":\"5f80a41e-a354-4bdf-9b21-42539ba00d98\",\"title\":\"Quick links\",\"audiences\":[],\"serverProcessedContent\":{\"htmlStrings\":{},\"searchablePlainTexts\":{\"title\":\"Quick links\",\"items[0].title\":\"\",\"items[1].title\":\"\"},\"imageSources\":{\"items[0].rawPreviewImageUrl\":\"\"},\"links\":{\"baseUrl\":\"\",\"items[0].sourceItem.url\":\"\",\"items[1].sourceItem.url\":\"\"},\"componentDependencies\":{\"layoutComponentId\":\"706e33c8-af37-4e7b-9d22-6e5694d92a6f\"},\"customMetadata\":{\"items[0].rawPreviewImageUrl\":{\"fixedWidth\":100,\"minCanvasWidth\":32767}}},\"dataVersion\":\"2.2\",\"properties\":{\"items\":[{\"sourceItem\":{\"itemType\":2,\"fileExtension\":\"\",\"progId\":\"\"},\"thumbnailType\":3,\"id\":2,\"description\":\"\",\"altText\":\"\",\"rawPreviewImageMinCanvasWidth\":32767},{\"sourceItem\":{\"itemType\":2,\"fileExtension\":\"\",\"progId\":\"\"},\"thumbnailType\":3,\"id\":1,\"description\":\"\",\"altText\":\"\",\"rawPreviewImageMinCanvasWidth\":32767}],\"isMigrated\":true,\"layoutId\":\"List\",\"shouldShowThumbnail\":true,\"hideWebPartWhenEmpty\":true,\"dataProviderId\":\"QuickLinks\",\"listLayoutOptions\":{\"showDescription\":false,\"showIcon\":true},\"imageWidth\":100,\"buttonLayoutOptions\":{\"showDescription\":false,\"buttonTreatment\":2,\"iconPositionType\":2,\"textAlignmentVertical\":2,\"textAlignmentHorizontal\":2,\"linesOfText\":2},\"waffleLayoutOptions\":{\"iconSize\":1,\"onlyShowThumbnail\":false},\"webId\":\"\",\"siteId\":\"\"}}},{\"id\":\"emptySection\",\"position\":{\"zoneIndex\":1,\"sectionIndex\":2,\"controlIndex\":1,\"sectionFactor\":4},\"addedFromPersistedData\":true},{\"controlType\":0,\"pageSettingsSlice\":{\"isDefaultDescription\":true,\"isDefaultThumbnail\":true,\"isSpellCheckEnabled\":true}}]",
