Hello **slowlytomm,** the error is on line 313 of your interactionHandler.ts file, nothing to do with railway. you're passing a string array where RoleColorsResolvable is expected. can you share the code around line 313? once i see it i can give you the exact fix

okay so based on the logs, the build issue is gone (the bot is running fine) the actual problem now is two different errors repeating over and over: the first one is error 40060 "interaction has already been acknowledged" , so here your code is calling `interaction.reply()` after already responding to the interaction (probably with a `deferReply` or another `reply` earlier in the same handler) , in `handleModalSubmit` around line 927, you need to use `interaction.editReply()` instead of `interaction.reply()` if you already deferred it the second error is error 10062 "unknown interaction" , discord interactions expire after 3 seconds if you don't respond your bot is taking too long before replying, so by the time it tries to respond, discord already killed the interaction. fix is to add `await interaction.deferReply({ ephemeral: true })` at the very start of your handler before doing any async work, then use `interaction.editReply()` at the end Hope this help you so to resume both errors are in the same handlers so fixing the defer/reply flow should solve both at once. can you share the code for handleModalSubmit and handleSelectMenuInteraction?

Hey, where can I find handleModalSubmit exactly? No clue where its at

found it , at the very bottom of your code there's the catch block in the main try/catch: ```ts } catch (error) { console.error('❌ Fehler in handleModalSubmit:', error); try { await (interaction as any).reply({ ... }) ``` this is the problem, your code already calls `reply()` successfully, but then something minor throws an error afterward, which triggers the catch block, which tries to call `reply()` a second time on an already-replied interaction , hence error 40060. the fix is simple, in that catch block replace `reply` with `followUp`: ```ts } catch (error) { console.error('❌ Fehler in handleModalSubmit:', error); try { if (interaction.replied || interaction.deferred) { await (interaction as any).followUp({ embeds: [createErrorEmbed('Fehler', 'Ein Fehler ist aufgetreten.')], ephemeral: true, }).catch(() => {}); } else { await (interaction as any).reply({ embeds: [createErrorEmbed('Fehler', 'Ein Fehler ist aufgetreten.')], ephemeral: true, }).catch(() => {}); } } catch (e) { ... } } ``` that one change should fix all the 40060 errors you're seeing
