> Hi All, Finally I discovered the problem and how to fix it, getting help from a developer colleague (thanks mate!). Below I summarize the problem found and the solution in case others find it useful: > > * Even though a dashboard is working correctly in your previous installation, when trying to import it from one installation to a new one, many times an error that prevents such importation appears. But that error doesn't provide much details of possible causes. > * To get more info about this problem: > * In the Internet browser, open the debugging console (in Firefox: press F12 key). > * In the 'Network' tab, search for and select the error in fuchsia (possibly a 422). > * In the right panel, select the 'Response' tab. > * Expand all the fields of the HTTP response JSON to see in which files and fields that build the dashboard structure the error is occurring. >  > * A common case is that the error is related to incorrect values that are assigned to the `template_params` parameter during the export. When exporting the dashboard, this field acquires the value `template_params: ''` . I think this parameter is related to _jinja SQL templating_ (https://superset.apache.org/docs/installation/sql-templating/). > * To fix it, unzip the exported zip file containing the dashboard structure. > * Search in the YAML files for the problematic field, based on the file paths and errors described in the JSON file obtained from the browser. >  > * In the case described, the value `''` should be replaced with `null`: `template_params: null`. >  > * Compress the directory with the dashboard structure back into the zip file. > * Import again the zipped dashboard into your new Superset installation. > * Error should not appear. > Maybe your error when importing a dashboard is not the same that the one described, but at least, you know how to start debugging it! > Hope it helps. > Thanks again for your support. Thanks for the trick!!!! Expand all the fields of the HTTP response JSON is the key ;) -- This is an automated message from the Apache Git Service.
